Chichester Harbour is a drowned river landscape of tidal channels and mudflats where Roman trade, Bosham's royal history, sailing and internationally important birdlife meet.
How it formed
Rising seas after the last Ice Age flooded river valleys and formed branching tidal creeks, islands, mudflats and salt marsh.
People and events
Romans used the sheltered water near Fishbourne, Harold Godwinson sailed from Bosham, and later fishers, shipbuilders and sailors worked its channels.
Local stories
Bosham's church and harbour are linked with Harold's voyage shown in the Bayeux Tapestry, keeping conquest history in the local waterside story.
What can be seen
Tidal flats, salt marsh, wooded shores, historic villages, working boats and vast winter bird gatherings remain.
Why it mattered
It matters because a heavily used south-coast harbour retains both internationally protected habitats and a long visible maritime history.
