Eynsford is a village in the district of Sevenoaks in Kent, England, set in the attractive Darent Valley on the banks of the River Darent at the foot of the North Downs. Its compact historic centre includes the ruins of the medieval motte-and-bailey Eynsford Castle, the Norman St Martin's Church and the working 18th-century Eynsford Mill, and it sits close to the important Roman site at Lullingstone (the Lullingstone Roman Villa).
Eynsford now combines village life with commuter links to London, yet retains independent shops, pubs and tea rooms and a lively community calendar of fetes and clubs. It is popular with walkers following the North Downs Way and visitors exploring the Darent Valley, and tourism around the heritage sites makes a useful contribution to the local economy while the place keeps a distinctly community-focused feel.
