Milestone C.325M South West Of Trevorva Cot Farm

This milestone dates from the 1820s or 1830s and stands on the verge of the lane leading from the A390 to Lower Tresawle, formerly part of the turnpike road. It is triangular in section with a flat top and is painted white with black lettering. The north-western face reads 'TRURO / 5' in Serif capitals, and the south-western face reads 'TREGONY / 2 ½'. A benchmark is located in the lower part of the Tregony face.

The Creed, Tregony and St Just Turnpike Trust was established in 1761 by an Act of Parliament to repair and widen the road from Creed to Ruanlanihorne and from Dennis Water to Trethem Mill. Few milestones from this trust survive. Tombstone-shaped milestones dating from shortly after the 1761 Turnpike Act exist south of Tregony, while the triangular design of this milestone is characteristic of the 1820s and 1830s.

Originally, the milestone was situated at a T-junction between the turnpike and a road to the north-west. The construction of the A390 has altered the road layout, leaving the milestone on a spur road.

The milestone is designated at Grade II for its intactness as a good example of an early 19th-century milestone, its original location, and its historical interest in illustrating the development of Cornwall's transport network, particularly its group value with other surviving milestones along the route between Truro and Tregony.
