Mersea Island coast walk

Mersea Island is an island in Essex, England, in the Blackwater and Colne estuaries to the south-east 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.

Barrow Hill is a hamlet in Essex, England. It is located on Mersea Island, approximately 2 km (1.2 mi) north-northeast of West Mersea near to where the Strood causeway meets the island. The hamlet is 33 km (21 mi) east-northeast of the county town, Chelmsford. Barrow Hill is in the borough of Colchester and in the parliamentary constituency of North Essex.

Mersea Fort, also known as Cudmore Grove Blockhouse, was an artillery fort established by Henry VIII on the East Mersea coast in 1543. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the River Colne that led to the town of Colchester.
