"Number 10" is the locale of British ministers since 1735. Every British knows that this building serves as the headquarters of the executive branch of the British Government.

Could you imagine how many important decisions have been taken behind this black door?

Unfortunately, most foreigners have no idea that 10 Downing Street has been the official residence and office of the First Lord of the Treasury for nearly 300 years. This post is held by the Prime Minister of the UK since 1905.

This can be interesting: Today most of its rooms serve as offices where the Prime Minister works, and where ministers and foreign ambassadors are met and entertained.
