Norwich very likely took its rise after the departure of the Romans, about A.D. 418, on account of the distracted state of the empire. Then, the camp or station at Caister being almost deserted, the few remaining Romans joined with the natives, and they became one people; and the situation of Norwich being thought preferable to that of Caister, many retired hither for the facility of fishing and the easier communication with the country. Caister, however, though almost deserted, kept up some reputation, till the river becoming so shallow, cut off all intercourse with it by water and reduced it to a place of no importance. After the departure of the Romans, the Angles from the opposite coast made themselves masters of this part of the island, and to them is chiefly owing the further progress of the city and its present name. “Northwic” signifies a northern station on a winding river, and may have been so called because of its being situated north of the ancient station at Caister. Norwich Castle was probably built in the reign of Uffa, the first king of the East Angles, soon after the year 575. About 642 it became a royal castle, and one of the seats of Anna, king of the East Angles, whose daughter Ethelfred, on her marriage with Tombert, a nobleman or prince of the Girvii (a people inhabiting the fenny parts of Norfolk), had this Castle, with the lands belonging to it, given her by her father. About 677, this Tombert and his wife granted to the monastery of Ely, which they had founded, certain lands held of Norwich Castle, by Castle guard, to which service they must have been liable before the grant, for, by the laws of the Angles, lands granted to the church were not liable to secular service, unless they were at first subject thereto whilst in secular hands, which proves that this was a Royal Castle in the time of King Anna.
