Over the years, it has undergone much extensive remodelling and reconstruction, most notably after being heavily damaged in the Second World War by enemy bombing during The Blitz where little remains of the original structure as designed by John Nash. It is Grade I listed on the National Heritage List for England. The house is open to visitors for approximately one month each summer, usually in August. The four-storey house is faced in pale stucco.
Clarence House is the official residence of Charles, Prince of Wales, and his wife Camilla, Duchess of Cornwall. Since 2003, the term Clarence House has been used as a metonym for the private office of the Prince of Wales. (The term St James's Palace had been used previously.) Clarence House was also the official residence of Prince William from 2003 until April 2011, and of Prince Harry from 2003 until March 2012. From 1953 until 2002 it was home to Queen Elizabeth The Queen Mother, and before her, it was the official home of Princess Elizabeth, the future queen.
The house was built between 1825 and 1827 to a design by John Nash. It was commissioned by the Duke of Clarence, who in 1830 became King William IV of the United Kingdom (reigned 1830–1837). He lived there in preference to the adjacent St James's Palace, an antiquated Tudor building which he found too cramped.
From William IV, the house passed to his sister Princess Augusta Sophia, and, following her death in 1840, to Queen Victoria's mother, Princess Victoria of Saxe-Coburg-Saalfeld. In 1866 it became the home of Queen Victoria's second son Alfred, Duke of Saxe-Coburg and Gotha (also Duke of Edinburgh), until his death in 1900.
Alfred's younger brother Prince Arthur, Duke of Connaught and Strathearn, Queen Victoria's third son, used the house from 1900 until his death in 1942. During his tenure, for a brief period in the 1930s, it was the location of the library of the School of Oriental and African Studies, until all universities in London were evacuated in 1939 and the school temporarily relocated to Cambridge.
During World War II, Clarence House suffered damage by enemy bombing during The Blitz (1940–1941). Following the death of the Duke of Connaught in 1942, it was used by the Red Cross and the St John Ambulance Brigade as their headquarters during the rest of World War II.
Following their marriage in 1947, it became the residence of Princess Elizabeth and her husband, Prince Philip, Duke of Edinburgh. Their daughter, Princess Anne, was born there in August 1950. In 1953, after the death of her father King George VI (d. 6 February 1952), Princess Elizabeth acceded to the throne as Queen Elizabeth II and moved to Buckingham Palace. Her mother, Queen Elizabeth The Queen Mother, and sister Princess Margaret moved into Clarence House. Also at the start of her widowhood, the Queen Mother purchased the Castle of Mey in Scotland as a summer residence.
Since 2002 (upon the death of Queen Elizabeth The Queen Mother), Clarence House has been the London residence of Charles, Prince of Wales, and his wife, Camilla, Duchess of Cornwall. Until their marriages in 2011 and 2018, respectively, it was the London residence of Prince William and Prince Harry.
