Basildon Park, Berkshire

This beautiful Palladian mansion features in the 2005 film adaptation of Jane Austen's Pride and Prejudice. It was built in 1776-83 by John Carr for Francis Sykes, who had made his fortune in India. The interior is notable for its original delicate plasterwork and elegant staircase, as well as for the unusual Octagon Room. The house fell on hard times in the early part of the last century, but was rescued by Lord and Lady Iliffe, who restored it and filled it with fine pictures and furniture.
