Description
The milestone in the garden wall of Glenroyd dates from 1764. It is a rectangular stone with a cambered head, standing approximately 1 meter high. The stone is painted white and features inscriptions in Sans Serif capitals: 'ST / AUSTEL / IIIIi / TRURO / XVIII', with the lettering highlighted in black paint.
Historically, this milestone was part of a series erected along the road from Grampound to Lostwithiel by the St Austell and Lostwithiel Turnpike Trust. Walter Treleavers provided the stones at a cost of 17 shillings each, including delivery. The distances marked were calculated from the 8-mile stone at the end of the adjoining Truro Turnpike Trust, resulting in the half-mile distances to St Austell that are recorded on all milestones in this group.
This milestone is designated for its historic interest as an intact example from 1764, remaining in its original position, and for its group value with other listed milestones along the Grampound to Lostwithiel turnpike route.
