The SIS Building, also commonly known as the MI6 Building, is the headquarters of the British Secret Intelligence Service, otherwise known as "MI6". It is known locally as Legoland and also as Babylon-on-Thames due to its resemblance to an ancient Babylonian ziggurat. It is located at 85, Albert Embankment in the south western part of central London, along the Albert Embankment on the bank of the River Thames beside Vauxhall Bridge.
