is much decorated with the initials CR. The window latches in the shape of the Prince of Wales's feathers commemorate the visit of the future King Edward VII. His son and daughter-in-law (later King George V and Queen Mary), visited in 1909. Long Gallery The Long Gallery was built by Sir Edward Herbert, following his purchase of the castle in 1587. It is constructed to a T-plan, an unusual design for an Elizabethan long gallery. Displayed in the gallery is a marble group of a cat and snake. It is probably Roman, dating between 1st century BC and 2nd century AD, although it could be an 18th-century fake. Representations of cats are rare in Roman art. The marble, quarried on Thasos was probably purchased by Clive of India for his wife on his visit to Italy in 1774. The gallery also contains a set of busts of the Roman Caesars. Their great weight led to their being moved from the Long Gallery by the Trust, due to concerns that they would lead the floor to collapse, but a full reconstruction of the floor has enabled them to be returned. Clive Museum When Robert Clive returned to England, his fortune of some £234,000 (£23 million today), made him the richest self-made man in Europe. According to William Dalrymple, much of the wealth amassed by Clive was loot that was illicitly collected after the Battle of Plassey. Several of Clive's acquisitions are on display in the Clive Museum at Powis Castle, along with items acquired subsequently by Edward and Henrietta, during Edward’s time working firstly for the East India Company and then as the Governor of Madras. These include Tipu Sultan's magnificent state tent, made of painted chintz; gold and bejewelled tiger's head finials from Tipu's throne; two cannons that are today positioned on either side of the castle entrance, and textiles, armour, weapons, bronzes, silver pieces, and collections of jade and ivory. The Clive Museum, opened in 1987 next to the ballroom in the North Range, has been the focus of controversy in the 2020s, due to the raised awareness of the links between country house collections and colonialism, as a result of the Black Lives Matter movement. The National Trust has committed to supporting reinterpretation of the collection. Listing designations In Wales Cadw is the statutory body with responsibility for the listing of buildings.
