Since 1754 the estate has belonged to the Petty-FitzMaurice family, whose head of the family is the Marquess of Lansdowne . Significant members of the family included William Petty, 1st Marquess of Lansdowne , the British Prime Minister in 1782/83.
The owners were known not only as influential politicians, but also as generous patrons of art and science: Joseph Priestley worked as a private tutor on the country estate for many years and isolated the element oxygen for the first time in Bowood House in 1774. The researcher Jan Ingenhousz died in Bowood Park in 1799.
The main house was demolished in 1955 for economic reasons after it had been empty for a long time. The existing buildings are still of an imposing size. Bowood House is open for tours.
