The Royal Lodge is a Grade II listed house in Windsor Great Park in Berkshire, England, half a mile north of Cumberland Lodge and 3 miles (4.8 km) south of Windsor Castle. It was the Windsor residence of Queen Elizabeth The Queen Mother from 1952 until her death there in 2002. Since 2004 it has been the official residence of Prince Andrew, Duke of York.
The Lodge dates originally from the mid-seventeenth century, there being a house on the site by 1662. By 1750 the small Queen Anne style brick house was being used in conjunction with the adjacent dairy. By this time it was known variously as the Lower Lodge, to distinguish it from Cumberland Lodge, then known as the Great Lodge, or the Dairy Lodge.
From the mid-eighteenth century it was home to the military topographer and artist Thomas Sandby (brother of the better known Paul), as Deputy Ranger of the Great Park. The house was then known as the Deputy Ranger's House.
It was enlarged by 1792, and was the home of Joseph Frost, the Park Bailiff, and then of the General Superintendent of Farms, after Sandby's death.
George, Prince of Wales (later King George IV), planned to rebuild Cumberland Lodge, after he had become Prince Regent. He used the Lower Lodge as temporary accommodation in 1812. Alterations and additions were undertaken by John Nash for the Prince of Wales.
The chapels of the Royal and Cumberland Lodges proved too small for the royal households in the early 19th century, and the Royal Chapel of All Saints was built in 1825 by Jeffry Wyatville. The chapel is less than a hundred yards from Royal Lodge.
