Sir Christopher Wren designed this house, which overlooks St James's Park, in the early 18th century, as the London home of the Duke of Marlborough and his wife, Sarah. The lavish entertainment of their friends, 'The Marlborough House Set' was legendary.
Since then it has been home for many members of the royal family, including Edward VII and Alexandria, when they were Prince and Princess of Wales.
Queen Mary lived here as a widow and her son, Edward VIII told her of this intention to abdicate in this house. She died here in 1953.
It has also been used as a meeting place for members of the Commonwealth of Nations since 1962, group tours are available by arrangement only.
