Chichester is a cathedral city in West Sussex, within the historic County of Sussex, South-East England. It has a long history as a settlement; its Roman past and its subsequent importance in Anglo-Saxon times are only its beginnings. It is the seat of a bishopric, with a 12th century cathedral, and is home to some of the oldest churches and buildings in Great Britain. Chichester today is a local government stronghold, with three levels of government being administered there. It is also a transport hub, and the centre for culture in the region, with a Festival theatre and two art galleries. Nearby Chichester Harbour, together with the South Downs and the city walls, provide opportunities for outdoor pursuits.
