Description

This is a late 18th century milestone associated with the turnpike road that was first established in the 1790s. It is a roughly-shaped, round-headed slate stone set into a rubblestone boundary wall by the roadside. The stone is inscribed with the text "C. CURIG 5 M. 5 1/2F./ CARNARVON/ 12M."

Milestone sits in one of the wettest parts of the UK, with an average of 1,310 mm of rain a year. This makes it wetter than 95% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 93% of listed buildings.

It experiences an average of 47 freeze-thaw cycles a year, more than 88% of listed buildings. Of these, 28 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
