Several areas of Bath had undergone development during the Stuart period; development increased during Georgian times, however, in response to the increasing number of visitors to the spa and resort town who required accommodation. The architects John Wood the Elder and his son John Wood the Younger laid out the new quarters in streets and squares, the identical façades of which gave an impression of palatial scale and classical decorum. Much of the creamy honey-coloured Bath stone used for construction throughout the city was obtained from the limestone Combe Down and Bathampton Down Mines owned by Ralph Allen (1694–1764).
