For purposes of sightseeing, East Anglia can be divided into distinct areas: the central area surrounding the ancient university city of Cambridge and including the towns of inland Suffolk; the southeast, taking in the ancient Roman town of Colchester and sweeping upward along the Suffolk Heritage Coast; and the northeast, with the region's capital, Norwich, the waterways of the Broads, and the beaches and salt marshes of the North Norfolk coast. North of Cambridge, the fenland city of Ely has a magnificent cathedral rising out of the flatlands. Farther north, in Lincolnshire, are the city of Lincoln, landmarked by its tall, fluted cathedral towers, and the historic ports of King's Lynn and Boston, which flank the shallow bay known as the Wash.
