The cairn at Thornworthy Down sits on the south side only a few metres from the edge of Fernworthy Reservoir.When it was excavated in the 1870’s it was found to contain two kists,the one in the photo in the centre and a smaller one on the southern side.The smaller one was removed and placed on display in the Torquay museum where it remained until 2004 when it was taken to the High Moorland Centre at Princetown.
