What is recorded here

Marblehill holds a long narrow gallery stretching ten metres through rolling pasture, its six northern and five southern sidestones still marking the chamber walls. Two roofstones slope above the ruins while a septal stone divides a short entrance from the main chamber, suggesting people built a deliberate passage for the dead rather than a random pile of rocks. The tomb sits two hundred metres south of another chamber, implying a buried neighbourhood where several families or generations claimed the same hill.

In rolling hilly pastureland, some 210m to the S of a portal-tomb (GA125-119----). This tomb comprises the ruins of a long narrow gallery (L 10m) aligned NE-SW. A septal-stone at SW separates a short portico (L c. 1.4m) from the remainder of the gallery (L 7.2m) of which six sidestones are in position at N, five at S, and a backstone at E. Two roofstones rest in a sloping position above the gallery walls. A single upright stone at N forms a doubling of the wall and a line of five stones to the S of the gallery may be the remains of an outer wall. The gallery is incorporated in an irregularly shaped mound on which lie a number of displaced slabs.

Wedge tomb, dating to the Late Neolithic or Early Bronze Age (c. 2500–1000 BCE). Its alignment and association with a nearby portal tomb suggest it is part of a broader ceremonial landscape.
