 Bombs often landed on the estate during the blitz of Bristol . In September 1940 , during a raid on the Bristol Aeroplane Company factory at Filton , bombs cut off the estate 's water supply , and during a later raid , one bomb badly damaged the lantern roof light over the hallway . In 1946 , after the end of the war , Lady Wraxall applied to the Ministry of Defence for a repair grant , but was turned down . As a result damp , and latterly birds , entered the house through the roof light , until the house came into the ownership of the National Trust and was repaired .
