Caernarvon Boroughs
The castle, town and borough of Caernarvon were founded by Edward I following the destruction of the residence there of the princes of Gwynedd at the conquest of Wales. The constable of the castle was ex officio mayor, and as constable from 1523 until his death in 1551 John Puleston more or less controlled the town. His successor John Harington II is not known to have visited Caernarvon and during his term of office the constableship was exercised by a local deputy, Robert Gruffydd.
