Aylsham is a historic market town and civil parish on the River Bure in north Norfolk, England, nearly 9 mi (14 km) north of Norwich. The river rises near Melton Constable, 11 miles (18 km) upstream from Aylsham and continues to Great Yarmouth and the North Sea, although it was only made navigable after 1779, allowing grain, coal and timber to be brought up river.
