Site 1 is a 45 m-long (148 ft) dolmen, most of which has been destroyed.
Site 3 is the remains of the earth embankment, still 43 m long. Most of its external stones are still there, eitherin situ or overturned. The chamber must have been located in the section that no longer exists.
Site 4 is an 80 m-long (260 ft) dolmen. It originally had about 100 external stones, 14 of which are still in situ, the remainder were put back during its restoration (some with dry stone walling filling the gaps). Thepassage grave consisted of a roughly 8 m-long (26 ft) chamber with 12 upright supporting stones and a pair of passageway stones. The original five capstones of the chamber as well as the capstone for the passage are missing. The location of the chamber in the dolmen is right at the end, likewise the side entrance to the chamber is offset well to the end, so that the site is classified as one of the so-calledHolsteiner Kammer ("Holstein Chamber") type.
Site 2 is a tumulus about 20 m in diameter in the centre of which the remains (the uprights and the joist (Schwellenstein)) of a passage grave are located.
