The Trenear Mortar Outcrop is a Scheduled Ancient Monument. It is unique being the only such monument in the South West

Formed from a living granite outcrop some 290 million years old. The granite here is the oldest in Cornwall being some 20 million years earlier than the remainder and is part of the Carnmenellis Pluton.

This Monument Stone serves to confirm the great antiquity and national importance of the location. We call this our TIN HENGE which is attributed to the later Bronze Age.
