Description

Loudoun Castle is a ruin of an extensive building constructed around 1807 in the castle style for the Countess of Loudoun and Moira, designed by architect Archibald Elliot. The structure incorporates parts of two older castles: a 15th to 16th century keep, which still stands four stories tall, and a section of a 17th century building.

Local climate

Loudoun Castle sits in one of the wettest parts of the UK, with an average of 1,350 mm of rain a year. This makes it wetter than 96% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 94% of listed buildings.

It experiences an average of 40 freeze-thaw cycles a year, more than 77% of listed buildings. Of these, 22 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.2°C per decade since 1991.
