today is the much altered 17th-century manor house. The key features of the castle include the original 13th-century gates and several pieces of art, including a Tudor copy of Hans Eworth's famous allegorical portrait of Sir John Luttrell, and a sequence of leather tapestries showing scenes from the story of Antony and Cleopatra. The castle also holds a piano that once belonged to the composer Vivian Ellis. The gardens surrounding the castle cover approximately and include the National Plant Collection of Strawberry Trees; the wider parkland beyond totals . Just to the south of the castle is the restored 18th-century castle watermill. In 2017 the castle received 209,245 visitors. Dunster Castle has been designated as a Grade I listed building and Scheduled Monument. The grounds are included on Register of Historic Parks and Gardens at Grade II*. The castle has required continuing maintenance work, in particular to its roof, itself an important historical feature. Efforts have been made to gradually redecorate the castle in a period style, using reproductions of original wallpapers and materials. The National Trust installed solar panels behind the battlements on the roof in 2008 to provide electricity and make the premises more environmentally friendly. This was the first time the National Trust have taken this approach to a Grade I listed building, and it is expected to save 1,714 kg (3,778 lb) of carbon a year. In 2015, the National Trust announced plans to make the 19th-century reservoir open to the public, and the reservoir was formally opened for viewing in April 2016.
