Birdham Pool was originally developed in the late 1930s from one of the last working tidal mill pools in Sussex. The Old Mill building still stands with the lock beside it. The picturesque setting and quiet friendliness is unique to the ‘Pool’ which was probably the first purpose built marina in England.

The ‘Pool’ is situated six miles from the entrance to Chichester Harbour on the southern edge of the area known as Chichester Lake. It is a non-tidal basin except at high water springs when the lock is operated on free flow at the top of the tide.
