Thorney Island, Emsworth, PO10 8DS

West Thorney, situated west of Chichester and south of the A27 road, is a small village and former civil parish on Thorney Island. The island itself is a peninsula that projects into Chichester Harbour in West Sussex and is separated from the mainland by a narrow channel known as the Great Deep. The village lies on the southern part of this peninsula, offering a quiet, rural setting with the harbour’s waters close at hand. The area’s character is shaped by its maritime geography and the presence of the British Army base that occupies much of the island, which has historically defined the local landscape. The PO10 postcode places it within the broader Emsworth community, linking it to nearby towns and services while retaining its distinct island identity.
