An 8m long, capstoned chamber surrounded by a ring of eighteen curb stones known as a 'peristalith'. Originally covered by a long mound what remains today is largely the work of restorers. When first excavated in 1868 the capstones had fallen into the chamber. These stones, including a porthole stone were lifted and placed as capstones. In 1919 the Société Jersiaise removed the porthole stone which had been incorrectly placed as a capstone and moved it to its current position at the eastern end of the chamber. Finds included a few flint flakes and pottery fragments.

In 2016 high winds caused the tree to the west of the site to split and fall on the western end of the dolmen dislodging the end capstone and one of the orthostats (see 3D model).
