Description

The Roman Bridge at Osterley Park is a late 18th-century structure, likely designed by Robert Adam around 1780. It features a rusticated stone façade and consists of a single segmental arch. On either side of the arch, there are pairs of rusticated Roman Doric half-columns, and the arch is adorned with mask keystones. The bridge also includes an entablature and a parapet, showcasing an interesting design influenced by Piranesi, making it an early neo-classical monument.

Local climate

Roman Bridge sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 91% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 86% of listed buildings.

It experiences an average of 29 freeze-thaw cycles a year, fewer than 67% 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.

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.
