Seasalter is a small village near Whitstable in the Canterbury District of Kent, England. Located close to the sea on the north coast of Kent, it faces the Isle of Sheppey across the estuary of the River Swale.
The Seasalter Flats are protected marshland, cut off by the A299 Thanet Way. The beach largely pebble-stone based. Seasalter Sailing Club has a clubhouse near the caravan park. Residents (not of the caravan park) include Gregg Wallace, Harry Hill and Janet Street-Porter (they live separately).
Three claims to fame. First, it came to prominence as a centre for salt production in the Iron Age and the resulting prosperity resulted in Viking raids on the area. Second, the church was dedicated to a martyred Archbishop of Canterbury, Alphege (Ælfheah). Third, in 1976, a free rock festival was held there after a forced move away from the chosen site in Tangmere.
