Kemsing is a Saxon 'ing', or 'place', associated with someone called Cymesa i.e. 'Cymesa's place'. It is first recorded in 822 as Cymesing
Princess Edith, daughter of King Edgar was born in Kemsing in 961AD. Following her death, she was canonised for the miracles associated with her. A well at the centre of the village named after her attracted many pilgrims.
There is evidence of Roman occupation with the remains of a water mill, or perhaps a villa, at the western end of the village and a tile works to the east.
Kemsing church was originally a wooden Saxon building, which was rebuilt with stone around 1060, and dedicated to St Mary the Virgin. A large tapering spire on top of a square tower was the result of remodelling in the 13th Century. In the late 19th century, with the re-acquisition of a resident vicar and some incoming gentry, major improvements were made to the church and the tone of line improved. The interior was designed by noted Victorian designer Sir Ninian Cooper in 1908.
Kemsing station was opened on 1 June 1874.
