Prior Park is a Neo-Palladian house that was designed by John Wood, the Elder, and built in the 1730s and 1740s for Ralph Allen on a hill overlooking Bath, Somerset, England. It has been designated as a Grade I listed building. The house was built in part to demonstrate the properties of Bath stone as a building material. The design followed work by Andrea Palladio and was influenced by drawings originally made by Colen Campbell for Wanstead House in Essex as well as the twelve sided plan form of the Roman theatre (of which the house's natural setting reminded Wood). The main block had 15 bays and each of the wings 17 bays each. The surrounding parkland had been laid out in 1100 but following the purchase of the land by Allen were established as a landscape garden. Features in the garden include a bridge covered by Palladian arches, which is also Grade I listed. Following Allen's death the estate passed down through his family. In 1828, Bishop Baines bought it for use as a Roman Catholic College. The house was then extended and a chapel and gymnasium built by Henry Goodridge. The house is now used by Prior Park College and the surrounding parkland owned by the National Trust. History Construction Ralph Allen, an entrepreneur and philanthropist, was notable for his reforms to the British postal system. He moved in 1710 to Bath, where he became a post office clerk, and at the age of 19, in 1712, became the Postmaster. In 1742 he was elected Mayor of Bath, and was the Member of Parliament for Bath between 1757 and 1764. The building in Lilliput Alley, Bath (now North Parade Passage), which he used as a post office, became his town house. Allen acquired the stone quarries at Combe Down and Bathampton Down. The unique honey-coloured Bath stone was used to build the Georgian city, and as a result he made a second fortune. Allen instructed John Padmire to build a wooden wagon-way from his mine on Combe Down which carried the stone down the hill, now known as Ralph Allen Drive, which runs beside Prior Park, to a wharf he constructed at Bath Locks on the Kennet and Avon Canal for onward transport to London.
