Description

Ivy Tower is a ruined, ivy-covered castellated tower that stands two storeys high and is constructed of rubble stone. The tower has an octagonal shape at the lower stage, which is buttressed, and transitions to a circular form above, featuring a string course between the two stages. The lower stage includes segmental-headed windows facing the cardinal directions and a segmental-headed doorway on the southwest side. The upper storey has windows and a doorway on the southeast side, which have 2-centred heads, and above these are small quatrefoil recesses. The castellated parapet of the tower projects forward. Inside, there is a fireplace located on the northwest side, with the chimney integrated into the castellations.

Local climate

Ivy Tower sits in one of the wettest parts of the UK, with an average of 1,380 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 96% of listed buildings.

It experiences an average of 28 freeze-thaw cycles a year, fewer than 69% of listed buildings. Of these, 12 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.
