Fort Belvedere, Surrey
During World War II, the Fort was used by the Office of the Commissioners of Crown Lands, which had been evacuated from their central London offices. After the War the house stayed empty. The Hon. Gerald Lascelles, younger son of Mary, the Princess Royal (daughter of King George V) was the tenant 1956-1975, on a 99 year lease.  He restored the gardens, and added a swimming pool, and tennis court. In 1976 the Emir of Dubai moved in. More recently the house is occupied by private tenants. The Crown Estate Commissioners remain the owners of the freehold, as the property is still part of the Great Park.
