Farlington Marshes is an area of reclaimed land in Langstone harbour. It was reclaimed from the harbour in 1771 and includes a larger part of what was formerly Binner's Island . Farlington Marshes is about 120 hectares in size and features both freshwater marsh and brackish marsh. It is a Local Nature Reserve and is a feeding ground for overwintering Brent geese. During World War 2 it was used as a starfish site acting as a decoy for Portsea Island. The control blockhouses remain on the marshes.
