Downing Street has been home to the most influential figures in the UK government for more than 300 years, including Winston Churchill, Margaret Thatcher, and Tony Blair. Number 10 (as it widely known in the UK), a Georgian townhouse completed in 1735, was designed by Christopher Wren, who also designed St. Paul’s Cathedral. In the 19th century, the buildings on one side of the street were demolished to make way for new government buildings, which now house the Foreign & Commonwealth Office.
The street was closed to the public in 1989. Visitors can now only glimpse the action from beyond iron railings, though the street reopens to guided tours on occasional weekends as part of Open House London. You might be able to spot the iconic front door from the top deck of a hop-on hop-off tour bus. Visitors often choose to join a guided walking tour or bus tour of London to learn more about the history of this famous address.
