*QUINBOROUGH, (Kent) at the S. W. point of the Isle of Sheppey, by the Medway, 4 m. N. of Milton, and 34 cm. 40 mm. from London, was made a Bor. by K. Edw. III. in honor of his wife; and he rebuilt its castle, which was repaired in the R. of Hen. IV. and again by Hen. VIII. and was standing in 1629; but was afterwards demolished. K. Edward impowered the inh. to chuse a mayor and 2 bailiffs yearly, who were to take the oath of allegiance before the constable of the castle; and to have Mts. on M. and Th. besides Fairs at Lady-day and St. James-tide; but the Mts. have been disused long since; and tho' it sends 2 members to Pt. it is become a poor place, the chief townsmen being alehouse-keepers and oyster-catchers. When the castle indeed was standing, many of its governors, who had the title of constable, were men of great consideration. The ground, where the castle stood, is moated round; but all that remains of it, is a well of 40 fathom deep. Here was, not very long ago, a good copperas work.
