Bellshiel Law long cairn. Photo by Northumberland County Council.

This prehistoric long cairn lies just below the summit of Bellshiel Law. The long axis of the cairn lies east-west and measures 109m long. The widest part of the cairn is 15m across at the east end and it stands up to 1.6m high. Only a small part of the cairn is covered with turf, for the most part it is bare stone. Excavations in 1935 showed that the cairn had a kerb of boulders around it and also discovered a rock-cut pit, thought to be a grave. No trace of internal divisions was found. A later stone enclosure has been built on the south side of the long cairn reusing stones from the cairn. Bellshiel long cairn is one of the earliest field monuments in Northumberland and dates to the Neolithic. This is a Scheduled Monument protected by law.
