🏝️ Mersea Island

Mersea Island is a tidal island in Essex, England, in the Blackwater and Colne estuaries to the south of Colchester. Its name comes from the Old English word meresig, meaning "island of the pool" and thus is tautological. The island is split into two main areas, West Mersea and East Mersea, and connected to the mainland by the Strood, a causeway that can flood at high tide.
