The Jacobean mansion that originally stood on this land was bombed and largely destroyed during World War II. In the 1950s, British architect and artist Sir Hugh Casson and his architect partner Neville Conder incorporated the surviving east wing into a new design for the King George VI Memorial Youth Hostel. The hostel’s garden is dominated by a vast lawn, which is lined with flowerbeds and features colourful shrubs, as well as a pond popular with Holland Park’s fowl and peacocks. Sunday visitors can expect a barbecue (weather permitting) as well as a charity performance by acapella group The Treblemakers (3.30pm-4pm). Open Sunday only, 9am to 5pm.
