Returning south from Respryn Bridge Helman Tor is a Neolithic site between Bodmin and Lostwithiel southwest of Sweethouse. The tor is at the northern end of a north-south granite ridge. Archaeological surveys have identified a series of low walls and levelled terraces on the tor. Within the enclosure are a number of level platforms thought to be house sites. Finds from the hilltop include greenstone axes, flint tools, stone querns and gabbroic pottery which confirm the Neolithic date for the construction and occupation of the tor.
