Castletown in Isle of Man, is a heritage harbour which has an Outer and Inner drying harbours. The harbour is mainly used by inshore fishing vessels, pleasure craft and occasional coasters. The Castletown Harbour Lighthouse hosts two Lighthouse(s) viz., Castletown Irish Quay and Castletown New Pier.
The outer harbour at Castletown is protected by a small breakwater on the end of which is a superb limestone built lighthouse, Castletown New Pier. The Lighthouse was built when Castletown was the capital of the Island and the harbour was more important than now.
The approach to the inner harbour carries a smaller Lighthouse, Castletown Irish Quay. The Lighthouse was referred to as "Pepper Pot" Lighthouse.
