Palladian
Norfolk
Derived from the buildings and publications of the Italian classical architect Andrea Palladio (1508-80). His manner was introduced to Britain by Inigo Jones in the early 17th century, and was revived by Lord Burlington and others in the 18th century, in both cases as a counter to the less strict or pure styles of the day. Its influence continued well into the 19th century.
