London’s most famous residence, and one of its best recognized landmarks, Buckingham Palace was built as a town house for the first Duke of Buckingham in 1705. Between 1824 and 1831, George IV commissioned John Nash to extend the house into a substantial palace, which was first occupied by Queen Victoria in 1837. The extensive front of the building was completed by Sir Aston Webb in 1913. The Palace is now home to the present Queen and the State Rooms are open to the public during summer. Many royal parks and gardens in London are also accessible to the public (see Royal Parks and Gardens).
