A chambered tomb is a megalithic structure used for communal burial during the Neolithic period. Megalithic means ‘made from large stones’ and these sites consist of a number of large stones set upright supporting a massive horizontal capstone to form a small chamber which was used to house the remains of the dead. Some may originally have been set within a stony mound or cairn. In Celtic areas they are known as quoits or dolmens.

Only recently recognised as a site type, tor enclosures are formed by a series of massive walls linking natural outcrops to enclose an imposing, usually granite, hilltop. Dating from the early Neolithic period, they are particular to south western Britain and are comparable to the causewayed enclosures found elsewhere in the British Isles.
