Folkestone, a seaport in Kent, 6 miles S.W. of Dover and 69 miles from London, is situated partly on the shore and partly on a cliff overlooking the sea, which has encroached at different times and swept away four out of the five original churches of the town. The one that is left has a central tower, and is conspicuous from its position on the cliff. There are a battery and three martello towers. The town is now a flourishing watering place, and owes much of its prosperity to the fact of the South-Eastern Railway having made it the point of their cross-channel service to Boulogne.
Folkestone was important in Roman and Saxon times, and suffered much from Danish inroads and French raids.
