Long mound
sometimes called a long cairn.
A cairn construction of stone piled together bounded by kerbs, placed over possible graves and wooded mortuary structures, dating back to the Neolithic. These have variable dimensions - though an arbitrary limit of more than 15m has been set, they may be nearer 100m in length, and of varying width. They are irregular in shape - though not rounded - and vary in orientation. Long mounds are usually on hillsides where views can be obtained, often of considerable distances in particular directions along valleys or across the sea, the remaining view may be limited. They are tentatively given a Neolithic date since they combine aspects of other Neolithic regional forms of burial such as long barrows, though they could have be a focus for later burials nearby.
