Description

Bryniau Tower is a round tower built from rubble stone, standing about 6 meters high with an internal diameter of 3.5 meters. The northeast side is missing, revealing wall cores that indicate the presence of former ground-floor openings. Inside, there is a ledge that may have supported a first floor, although two likely beam sockets are positioned slightly higher. The upper stage features what could be the reveal of a former window.

Local climate

Bryniau Tower sits in a wetter-than-average part of the UK, with an average of 1,100 mm of rain a year. This makes it wetter than 87% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 76% of listed buildings.

It experiences an average of 34 freeze-thaw cycles a year, fewer than 51% of listed buildings. Of these, 18 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.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
