gas lighting-supported by a gas plant in the basement-central heating and new kitchens were installed within the castle. The roof of the Great Gatehouse was raised to create a more uniform sequence of battlements, and a large hall for gatherings of the local farmers installed. A new wing of servants' quarters and offices were sunk into the hill, spread over two floors leading away from the main part of the mansion. Internally, Salvin knocked through existing rooms to create the Outer Hall, a new gallery on the first floor, a billiard room, a new library and a drawing room. Much of the wooden 17th-century panelling in the parlour and the hall had to be stripped out as part of the renovations. As part of his work, Salvin appears to have used a number of rolled wrought-iron beams to span the resulting structural gaps in the building, an advanced use of that technology for the time. The house was refurnished with newly bought 16th and 17th-century artwork, two brass Italian cannons and a stuffed polar bear. Alexander Luttrell, who inherited Dunster Castle in 1910, chose to live at East Quantoxhead instead, and it was left empty until his son Geoffrey reoccupied the castle in 1920, redecorating some of the rooms in a contemporary style and building a polo ground alongside the castle. The castle and the surrounding countryside at this time was very popular with the Luttrells for fox hunting and shooting. During the Second World War the castle was used as a convalescent home for injured naval and American officers between 1943 and 1944. Alexander died in 1944, and the death duties proved crippling to Geoffrey. In 1949 he sold the castle and 3,480 hectares (8,600 acres) of the lands to the Ashdale Property Company, retaining a tenancy of the castle for himself. The Crown Estate bought the estate from Ashdale and sold the castle back to Geoffrey in 1954. His son Colonel Walter Luttrell lived away from Dunster, and following the death of his mother – the last Luttrell to live in the property – gave the castle and most of its contents to the National Trust in 1976. Today Dunster Castle is operated by the National Trust as a tourist attraction. Little remains of the medieval castle except for the Great Gatehouse and the remains of several towers in the Lower Ward; the heart of the modern castle
