  Location of Coultershaw Beam Pump in West Sussex | |
Coultershaw Bridge is a rural community situated 1.5 mi (2.4 km) south of the town Petworth in West Sussex, England where the A285 road from Petworth to Chichester crosses the River Rother.
Between 1792 and 1888, there were also wharves and a lock at Coultershaw on the Rother Navigation. Until the 1970s, a water mill stood on the river housing a beam engine which was originally installed in 1782 by the 3rd Earl of Egremont to pump water from the river to Petworth and his home at Petworth House. Following the demolition of the mill, the Coultershaw Beam Pump was restored to working order and is now a Scheduled Ancient Monument, which is open to the public on summer weekends.
