The first record of the existence of a settlement at Plymouth was in the Domesday Book in 1086 as Sudtone, Saxon for south farm, located at the present day Barbican. From Saxon times, it was in the hundred of Roborough. In 1254 it gained status as a town and in 1439, became the first town in England to be granted a Charter by Parliament. Between 1439 and 1934, Plymouth had a Mayor. In 1914 the county boroughs of Plymouth and Devonport, and the urban district of East Stonehouse merged to form a single county borough of Plymouth. Collectively they were referred to as "The Three Towns".
