Few London addresses are as famous as 10 Downing Street, a Grade I listed Georgian townhouse and the official residence and office of the British Prime Minister since 1735. Centuries of government meetings, important decisions and more than a few scandals have taken place behind the property’s iconic black door (which can be opened only from the inside and even the Prime Minister is not given a key) and former residents have included everyone from Winston Churchill to Margaret Thatcher to Tony Blair.
For security reasons, access to Downing Street is limited to government officials only and visitors can do little more than peek through the police patrolled iron gates, but it’s still a popular inclusion on visitor’s itineraries, and there’s always the chance of spotting the Prime Minister himself. Those wanting to get a closer look can follow the video tour on the Downing Street website or, if you’re lucky, join one of the Open House London tours that take place over one weekend a year. Keep an eye on next door too - 11 Downing Street is the official residence of the Chancellor of the Exchequer and sees a steady stream of British politicians through its doors.
