Seaford is a small town lying south of Lewes on the coast, and on the opposite side of the river Ouse from the port of Newhaven.
Seaford used to have a fine harbour which by the late 1500's had silted up, making landing impossible, and the harbour was moved to nearby Newhaven about 2 miles to the west some time before 1565.
Seaford is on the coast, and although the beach is made of shingle it is very pleasant.
