Prior Park is a Palladian house, 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 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 The design followed work by Andrea Palladio and was influenced by drawings originally made by Colen Campbell for Wanstead House in Essex.
