The Beaulieu Palace House is a 13th century house located in Beaulieu, Hampshire. It was originally built in the 13th century as the Great Gatehouse of Beaulieu Abbey and has been the ancestral home of a branch of the Montagu family since 1538, when it was bought from the crown following the Dissolution of the Monasteries by Henry VIII.
Although still home to the current Lord and Lady Montagu, parts of the house and gardens are open daily to the public. It is a member of the Treasure Houses of England consortium.
