Number 10 Downing Street is one of the most famous addresses in the world and the most photographed door in England. Originally built in 1680, it has been the official residence of British prime ministers since 1735. Behind the famous black door, Number 10 is actually made up of two houses joined together, a cheap terrace house at the front and a much grander building, overlooking Horse Guards Parade at the back. Today the residence is an office for the Prime Minister, a meeting place for the Cabinet, a venue for state events and, in a private flat on the second floor, a home for the Prime Minister’s family. Traditionally, the adjacent property (number 11) is the official residence of the Chancellor of the Exchequer. Although Downing Street is closed to the public, you can catch a glimpse of it from the gates and may even see members of parliament coming and going! However, it’s safe to say that a visit here won’t fill a whole day, giving you the opportunity to explore the abundance of other attractions that are just minutes away. These include Churchill War Rooms, The Household Cavalry Museum, Big Ben or you can take a stroll around St James’s Park. All of this is easily accessible with Westminster tube station just a short walk away.
