Chertsey is a town in the Borough of Runnymede, Surrey, England, 29 km southwest of central London. The town grew up around Chertsey Abbey, founded in 666 AD, and was awarded a market charter by Henry I. A bridge across the River Thames was first constructed in the early 15th century. The River Bourne runs through the town to meet the Thames at Weybridge.
The Anglican church has a medieval tower and chancel roof. The 18th-century listed buildings include the current stone Chertsey Bridge and Botleys Mansion. A curfew bell, rung at 8 p.m. on weekdays from Michaelmas to Lady Day, is associated with the romantic local legend of Blanche Heriot, celebrated by a statue of the heroine and the bell at Chertsey Bridge. The green spaces include the Thames Path National Trail, Chertsey Meads and a round knoll with remains of a prehistoric hill fort known as Eldebury Hill. Pyrcroft House dates from the 18th century and Tara from the late 20th.
Train services from Chertsey railway station to and from London Waterloo are operated by South Western Railway. The town is within the M25, which is accessible via junction 11.
