Sovereign Harbour is a development of the beachland in the seaside resort of Eastbourne, to the east of the town centre. Opened in 1993 and formerly known as The Crumbles, the marina now consists of five separate harbours, (North Harbour, South Harbour, West Harbour, Outer Harbour and Inner Harbour), a retail park and several housing projects with both permanent and holiday properties. Sovereign Harbour is Northern Europe’s largest composite marina complex.
