Innisidgen is the site of two Bronze Age entrance graves on the island of St Mary's in the Isles of Scilly [1]. The two burial monuments, (Upper and Lower Innisidgen) lie on a steep slope of Innisidgen Hill overlooking Crow Sound with a view towards the Eastern Isles [1]. Innisidgen Hill is a scheduled monument on the Isles of Scilly, north east of Hugh Town [1]. Lower Innisidgen lies near the bottom of the northern slope of Innisidgen Hill [1]. This grave is more damaged than the upper grave and has only two of its original capstones [1]. Upper Innisidgen, also known as "The Giant's Grave", is one of the best preserved entrance graves on Scilly [1]. The entrance grave consists of a slightly oblong mound of earth and rubble measuring 9m by 8m, and is 1.8m in height [1]. The mound covers an intact burial chamber with an entrance at the eastern side of the mound [1].
