Coultershaw Wharf and Beam Pump  Coultershaw Bridge is a rural community situated 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. In Saxon times the locality was known as "Cuóheres Hóh", meaning "Couhere's spur of land". By 1240, the name was given as "Cuteresho". Since then, the name has been spelt in many different ways, including "Cowtershall" (1535), "Cowtershawe" (1564), "Coultersole" (1716), "Cowdersole" (1779), "Cowters Hall" (1795) and, finally by its present name in 1800. The Domesday Book, compiled in 1086 records a mill at Petworth, which almost certainly referred to the mill at Coultershaw. By the mid-13th century, the mill was owned by the Percy family, and in July 1240, William de Percy endowed the priory at Shulbrede near Linchmere with the mill at "Cutersho" while retaining the right to "the free grinding of all kinds of corn which shall be used in his house at Pettewurth". He also granted the priory the right to take earth from his land near the mill to repair the mill-pool when necessary, and granted that the "villeins" at Tillington and Petworth should give the prior up to three days' aid each year to repair the mill-pool. In consideration for the transfer, the prior was to pay Percy or his heirs two marks of silver each year until such time as Percy gave "ten librates of land in a suitable place in Sussex or Yorkshire" to the prior, after which the mill would revert to Percy. The Percy family failed to exercise their right to reclaim ownership of the mill; in the Sussex Hundred Rolls of 1275, the mill was shown as belonging to the priory, with an annual value of £10.
