Gallery grave

A Gallery grave, also known as an Allée couverte tomb is a form of Megalithic chamber tomb where there is no divide between the burial chamber itself and the entrance passage. Two parallel walls of stone slabs were erected to form a corridor and covered with a line of capstones. The rectangular tomb was covered with a barrow or a cairn. Most were built during the fourth millennium BC, though some were still being built in the Bronze Age.

They are distributed across Europe and they are usually sub-divided by period, region and also into more generic types of chambered long barrows, chambered round barrows , chambered long cairns and chambered round cairns . Examples are known in Catalonia, France, the Low Countries, Germany, The British Isles, Scandinavia, Sardinia and southern Italy.
