Westerham is a town and civil parish in the Sevenoaks District of Kent, in South East England with 5,000 people.
The parish is south of the North Downs, ten miles west of Sevenoaks. It covers 5800 acres (2320ha). It is recorded as early as the 9th century, and was mentioned in the Domesday Book in a Norman form, Oistreham. Ham is Old English for a village or homestead, and so Westerham means a westerly homestead.
The River Darent flows through the town, and formerly powered three watermills.
There is evidence that the area around Westerham has been settled for thousands of years: finds such as a Celtic fortification (c 2000 BC) and a Roman road are close by, along with the remains of a Roman encampment just past the ruins a of tower south of the town at the summit of Tower Woods.
Interesting fact:In what is now called Quebec House is the "childhood home" of General James Wolfe, who led the British forces on the Plains of Abraham
