Description

The aqueduct, known as No. 87, carries the Lancaster Canal, which was opened in 1797 and engineered by John Rennie, over the River Conder. It is constructed from punched sandstone blocks and features a single segmental arch with a straight string course above, flanked by piers. Above the arch, there is a battered retaining wall with a concave plan, and the piers extend to just below the top of a solid parapet that includes a string course.

Local climate

Aqueduct (No.87) sits in one of the wettest parts of the UK, with an average of 1,370 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 97% 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.

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.
