Burial Chambers

Burial Chambers (3000BC – 2000BC)

The Neolithic period starts from 4000BC, around the time when communities started farming and settling in an area, breaking away from the hunter-gatherer way of living. As small tribal communities settled, the population also grew, thus giving more importance to agricultural farming, creating new farmland and transforming the landscape around them.

It is around this time when Megalithic structures were constructed. Chambered tombs such as passage graves were mainly constructed from around 3500BC for the communal burial of the dead. Some would have been multiple burials covered by an earth barrow or stone cairn. Examples of these kinds of burial chambers are to be seen at Bryn Celli Ddu and Barclodiad y Gawres on Anglesey,  probably the most well known of the burial chambers we have in this part of North Wales.

Types of Burial chambers

  • Passage grave – has narrow passage made of large stones, some have multiple graves (some have corbelled roofs)
  • Chambered tomb – covered by earth or barrow (mound)
  • Chambered cairn – a chamber covered by stones (some may be passage graves)
  • Dolmen (Cromlech) – usually single chambered tomb with flat capstone (portal tomb) – (ancient term for burial chamber)
  • Barrow (Tumulus) – a rounded earthen mound – bronze age, covering a burial
  • Long Barrow – a long Neolithic mound covering multiple burial chambers
  • Cairn – a rounded mound of stones, covering a burial

Cairns are not mentioned in my list, as there are too many scattered around on most hilltops. These usually consist of piles of stones covering a probable later Bronze Age to Iron Age burials. They are not regarded in the same high regard as the larger Neolithic stone built burial chambers.

Below is a list of all the known burial chambers in the area

I have included an O/S number on all historical sites to enable everyone to locate using an O/S map.

    Some areas may be on private land and permission to roam may be required.
     There are public footpaths leading to most places.
    Safety and care must be taken at all times, as some areas are difficult to get to due to hills and slopes that may lead away from paths.
