              Passage mounds rank among the largest 
              prehistoric structures left by the megalithic builders. They are 
              strongly associated with astronomy, and share constructional 
              features with both dolmens and Pyramids.

				There are several substantial passage-mounds across western Europe, some of 
    which can have only been built with the support of a large-scale 
    organisation of skills, labour, materials etc. The fact that the majority of 
    the largest European passage-mounds were built at the same period of 
    prehistory (c. 3,500 - 3,000 BC), combined with similar construction 
    principles, art, design and orientation of passages, leads one to look at 
    the development of these structures at this particular  period of 
    prehistory as representing the result of an establish and structured 
    society.

              Passage Mounds - Form and Function. | 
             
           
    
        
          
    
        
    
    
          
            
          
    
        
    
    
    
By definition, a passage-mound is... 'A mound - with a passage in it...'.  
    
          
      
    
            
            
           
			
    
          
      
			
			
			The passages of all the 
significant European mounds are invariably orientated so as to mark significant 
celestial events (such as the equinoxes, solstices, and lunar minor and major 
stand-stills), allowing light to enter the interior of the mound at fixed 
moments of the year only. 
    
          
    
    
          
    
          
    
        
    
    Passage mounds are generally considered to have originated from 
the basic circle or henge monuments, such as at Brynn 
Celli Ddu, in Wales. However, there are components in the design of the 
mound which can be seen in other megalithic structures. The principle of 
orientating a structure to allow sunlight to enter it at selected 
times of the year is echoed in the construction of Egyptian monuments.  
	 
	The internal masonry that 
composes the  passage and chamber of European passage mounds also shares 
a strong similarity to that of dolmens, which themselves range from a simple 
dolmen ( chamber) 
to a dolmen including a passage (Allee 
Couverte).
        
    
	  
    
           
    
    
  
    
    
        
    
          This picture is of the Zambujeiro passage-mound in Portugal, which has 
had a large part of the mound removed revealing the passage masonry, showing 
strong similarities with the Allees-couverte of France . 
    
    
        
    
         
    
    
          
    
    
        
          What's in a name? 
    
    
For a long time, passage-mounds, along with several 
other ancient structures, were assumed to be 'funerary' structures. For this 
reason, these structures were termed 
        
    
     
    
    
        
    funerary mounds, passage graves
    etc, but human remains, when there were any have almost invariably revealed 
themselves to be from a secondary use. It is no longer possible to ignore the 
fact that there is also a strong astronomical influence in the design of the 
particular structures. In the Boyne valley, Ireland - the passage-mounds and their 
surrounding structures have been shown to jointly offer an accurate means of 
calculating the most significant moments in both the lunar and solar cycles.

    Tara Hill, Ireland. 
    
    The 'Mound of hostages' - on the Hill of Tara 
    in Ireland is a legendary sacred site (The Sacred Heart of Ireland). 
    Along with many other passage mounds, it is orientated to allow the passage 
    of sunlight to 'penetrate' its body only once each year. The connection 
    between the female Earth-goddess and the male Solar-God is obvious.

				There is little argument to 
              the notion that, as the menhir is to the male, so the passage 
              mound is to female. The association is well documented and can be 
              seen around the ancient world. But to what extent is the 
              association with passage mounds and the female form valid? - What 
              purposes did they serve, beyond a possible representation of the
              	earth-mother-goddess. The oracle centres of ancient Greece were 
              traditionally frequented by females called 'Sybils' who were 
              associated with serpents and the underworld...

 The Logistics of Passage mound Building. 
    
              
    
    
The building of such large passage mounds as those seen 
at the Boyne valley, Gavr'inis, Maes-Howe, Zambujeiro etc, would have been no 
easy endeavour, with man-hours estimated in the thousands for each 
structure. 
    
     
    
    
              
        In addition, the variety of skills, organisation and levels of energy required to accurately 
achieve such constructions, suggests the presence of a highly organised society. 
We are told by the guides at
    
    
    
        
    
              
Newgrange that this structure alone took  an estimated 
50-60 years to build, (the length of 
    
    
    
two 
average Neolithic lifetimes), effectively ruling it out as a 'funerary' 
structure....

            When were they built : 
        
             
    
    
        
    
          The earliest passage 
          mounds are recorded in France, Ireland c. 4,700 - 4,600 BC. At 
          this early period of time all the classic elements of the passage 
          mound were already in place. At Kercado in France, the passage mound 
          was built orientated towards the midwinter sunrise (6), while in 
          Ireland, they appeared only 100 years. 
              
Recent research 
              in France has revealed that several of the passage-mounds in the 
              Carnac region were  constructed around 3,300 BC, by people 
              who used and absorbed the megaliths from existing monuments made 
              by a previous megalithic culture 
            (over a thousand years earlier), into the megalithic structures  which we see today. 
              Their early appearance in southern Europe and consequent 
              re-introduction at 3,300 BC in France, Wales, and 3,200-3,000 BC 
              in Ireland and Scotland offers a suggestion of coastal migration 
              northwards. 
         
    
    
    
      
    
    
    
            
    
        
        
    
    Passage-mounds and Stone Circles: 
     
    
        
        
    The primal 'Mound of Creation'.
    There were 
    several types of prehistoric 'mound' to be seen on the prehistoric landscape. 
    Many of them are simple 'cairn's' or 'barrow-mounds' and are solely 
    associated with funerary rituals. However, there are also several other larger 
    mounds which appear to have served other functions, including the observation 
    of astronomical events. 
         
    
    
    
    
    
        The 
    numerous 'Beacon' Hill's in Britain have been mentioned above, and tradition and 
    observation shows that they  served the same function as passage-mounds but to a larger 
    audience through the lighting of beacon fires in lines on hill tops across 
    the open landscape. This too can be seen as a multi-functional act, both 
    demonstrating a physical connection with the cycles of the cosmos through 
    aligned landscape features, at the same time as connecting observers. 
    
    
    
        
    
    The
    Boyne-valley passage mounds were each 
    orientated so that the sunlight reached along the passages and into the 
    central chambers at very specific moments of the solar and lunar cycles. In addition, The same is true of
    Maes-Howe on the Orkneys,
    Gavr'inis in France,
    Bryn-Celli-Ddu in Wales and
    Zambujeiro in Portugal. All of these 
    passage mounds were constructed according to a set of basic astronomical 
    requirements, which at the same time as enabling the builders to measure the 
    solar and lunar cycles accurately, physically connected them to the 
     
    
            beating heart of their 
    universe.
    
    
      
    
          It is proposed that 
			these mounds were a symbolic representation of the primal 'Mound of 
			Creation', rising from a watery mythological past. The Maes Howe 
			mound above is connected to the ceremonial landscape of the Orkneys 
			through the close proximity of the Stennes circle, and within sight 
			of that, the larger Brodgar circle, a combination which appears to 
			have a common thread at several other western European megalithic 
			complexes: (Avebury/Silbury Hill, Gavr'inis-Er-Lannic, Zambujeiro-Almendres, 
			Ggantija/Xaghra). Regional variation on this theme has resulted in 
			several combinations: In Ireland, Tara Hill shows the same features 
			combined in the same ceremonial setting, only with the mound in the 
			centre of the circle, Newgrange mound was built over an existing 
			Stone circle, and Avebury has two circles built within it. This 
			association of a prominent mound and associated circle/s can be seen 
			to be one of the basic features of several of the (contemporary 
			Neolithic) western-European ceremonial arenas. There are several 
			other more specific similarities which suggest a contact along the 
			Atlantic coastline of Europe between these civil-scale ritual 
			complexes.

            While the outsides of many 
            passage-mounds have suffered from the fancies of the restoration 
            team, the insides have remained relatively untouched, and it is here 
            that we find several structural and artistic similarities between the European 
            passage-mounds. The following examples include some of the 
            largest and well known passage mounds in Europe.
    
              
    
      
    
            Similarities in Design: 
    
      
    
            
          Raised internal chambers: Both the Newgrange and 
          Gavr'inis passage-mounds have artificially raised internal chambers. 
          In Newgrange, this elevation of the chamber reduces the entry of light 
          into the central chamber as the following diagram illustrates. 
        
                    
                    
                      
          
          
                    At Newgrange, the light-box 
                    is used along with other construction features (such as the 
                    passage narrowing and undulating along it length and a 
                    subtle increase in altitude towards the centre),  which 
                    combine to focus the rays of the 
                    sun along the passage into a small, narrow beam of light, 
                    which is visible for only a few minutes on a few days 
                    around the winter solstice. As well as illustrating the 
                    astronomical nature of the structure, the inclusion of such 
                    a specific set of designs highlights the importance of accuracy to the builders.

             Light-Boxes

    The incorporation of light boxes into megaliths is one of the 
    few direct proofs of the link between megaliths and astronomy, as 
    their purpose was the manipulation of light into the passage mounds at 
    certain times of the year only. In Egypt, the earliest pyramids all contain 
    'polar-shafts', and on Malta, the 'Temples' were orientated towards the 
    solstices and equinoxes. In Britain, all the known passage-mounds 
    containing light-boxes were also  aligned with solar events, (i.e. the 
    equinoxes or solstice)

			Newgrange, Knowth, Dowth, Fourknocks and Maes-Howe all have cruciform chambers

            (And 
			the 
            internal layout of the Maltese temples also show strong 
            similarities). 
            The exact function/purpose of the cruciform design is still unknown, 
            but there are some common threads which may offer a clue as to 
            their original purpose. 
			  
    
          
            European Cruciform chambers are frequently 
            associated with astronomical orientation.They are distinguished by a long 
          passage leading to a central chamber with a corbelled roof. From this, 
          burial chambers extend in three directions, giving the overall 
          impression in plan of a cross shape layout. Some examples have further 
          sub-chambers leading off the three original chambers. The network of 
          chambers is covered by a cairn and lined outside with kerb-stones. 
        
        
          A common trait is megalithic art 
          carved into the stones of the chambers' walls and roofs. Abstract 
          designs were favoured, especially spirals and zig-zags.

            'Steward of the Estate of Akhetaten' and 'Royal Scribe' at 
            Akhetaten' during the Amarna Period, was also cruciform in 
            shape. It is interesting to note that here too a bowl was present. 
            'The shrine opening from the very back of the 
            broad hall on the center axis of the tomb was undecorated, though a 
            seated statue of the tomb owner was cared at is back. However, this 
            is now badly mutilated. A libation basin was cut into the floor in 
            front of the statue'.

        The same cruciform symbolism is seen around the ancient world, 
    where it is often associated with the 'World-Tree' or the Sun.

          The Maltese temples are believed to have been 
          originally covered over, which would have rendered them with 
          essentially the same exterior design as the other other European 
          passage mounds.  
            
    
            
        
            
    
        
          The Maltese temples, whilst retaining a essentially 
          internal cruciform shape, are rounded in the same way as the 
          earth-mother figurines found across the island. It has been suggested 
          that this interior design can also been seen at other prehistoric 
          constructions such as Skara Brae, on the Orkneys and over 60 Neolithic 
          houses across the British Isles.

    It has been noted that the cruciform chambers of several 
    large, prominent passage mounds contain large, stone-cut 'offering'-bowls or 
    'libation-bowls'.

    The bowls at the Boyne valley (above) were found to have 
    funerary deposits in them, although it is not clear if that was what their 
    original purpose was. In the case of the Dowth bowl, it has been shown from 
    its dimensions that the passage (and therefore the mound), had to have been 
    built around it. The engravings on both the Newgrange and Knowth bowls 
    suggest that they are contemporary too.

        The Kerbstones from Newgrange K-52 (left) and
        Gavr'inis, France, right share several 
        symbolic designs.  
          
    
          
        Stone SE4 at Knowth has a series of 
        crescents running down the side, a design similar to that found on the 
        rear stone inside Le Table des 
        Marchands' passage mound, (nearby and contemporary with 
        Gavr'inis).  
            
        
          It has also been noted that there are several distinct similarities between 
          the art of the 
          Boyne Valley complex and the Orkneys 
        complex as 
          the following pictures illustrate.

          stone, Orkneys (right). 
            
          Similar Art can be seen on Malta. The 
          contemporary images of the prehistoric Maltese temples show them as 
          being covered over, which, when combined their internal cruciform 
          design and the fact that they were generally orientated to the same 
          moments of the year reveals a set of common themes with the western 
          European passage-mounds.

        The

         At 4,700 BC, The Kercado 
        passage-mound is one of the earliest examples in Europe. It was 
        carefully orientated towards the midwinter sunrise. 
          
        
        The Boyne-Valley passage-mounds. 
              
        The Boyne Valley complex have been shown to have been 
        built so as to be orientated and aligned amongst each other so as to 
        mark several important solar and lunar events. Combined with the 
        inter-visibility of structures at 
        Loughcrew and Tara hill, both of 
        which were important megalithic sites in their own right, and both of 
        which also contain astronomical markers, and we are able to begin to see 
        that there is no doubt that astronomy was important to the builders of 
        the large Irish passage-mounds of 3,200 BC. It is suggested that this 
        network of inter-visible sites would have operated like a giant 
        'calendar' for the inhabitants at the time. (1)

             Research in France has 
            revealed more than one building phase of passage-mounds in the Carnac region. 
                  The Neolithic builders of 3,300 BC 
            absorbed the monuments from an earlier megalithic culture into their 
            own structures (from over a thousand years before).

            dated at around 3,300 BC.

             The 
            Irish passage mounds: Ireland has the 
            highest concentration of passage mounds, and they have been shown to 
            serve a specific function, namely that between them, they functioned  
            provided the locals with an accurate calendar of all the major solar 
            and lunar events throughout the year. (1) 
    
            The Irish passage mounds from the 
            Boyne valley region, were built at around 3,200 BC 
            (2), the same time as the French were building 
            theirs.

                  Portuguese 
                  passage-mounds: There are several passage mounds in 
                  Portugal ranging from full sized, 50m diameter mound of 
                  Zambujeiro to the more frequent but smaller mounds such as the 
                  Orca mounds by the Mondego river. 
                   
                  The Portuguese passage 
                  mounds present themselves as a unique hybrid of both dolmen 
                  and passage-mound, with several of them having never been 
                  fully covered.  
                  Although there are several 
                  different variations on the design of the Portuguese mounds, 
                  they have a style that remains unique to themselves which is 
                  that the stones supporting the capstones (invariably between 7 
                  and 9), are placed with the front stones seemingly resting on 
                  the larger stones at the rear of the chamber. This style of 
                  construction is not seen elsewhere in northern Europe where 
                  the stones are placed upright independently of each other.
                   
                  
                  Another noticeable fact with 
                  many of the Portuguese dolmens and Passage-mounds is that a 
                  great many of them have the top-half of the stone on the N-E 
                  of the chamber missing. (Pers. Obs.)

         Spanish 
                  Passage Mounds: Spain has several 
                  prominent passage mounds, including arguably the largest one 
                  in Europe.  
                  
                  The
                  Cueva de Menga complex include three 
        substantial passage mounds. 
        Cueva de Menga is considered to be one of the largest 
        such structures in Europe. It is twenty-five metres deep, five metres 
        wide and four metres high, and was built with thirty-two megaliths, the 
        largest weighing about 180 tonnes.  
        The entrance to the dolmen faces the 
        anthropomorphic Pena de los Enamorados in the distance.
