MI6 building - Vauxhall, London and Riverside
This is the MI6 building on the Albert Embankment, as seen from the River Thames. (I was in Millbank)
It is actually called the SIS Building, but is more commonly known as the MI6 building. It is the headquarters of the British Secret Intelligence Service (otherwise known as "MI6").
Within the intellegence community it is known as Legoland or as "Babylon-on-Thames" because it resembles an ancient Babylonian ziggurat.
It is located at 85, Albert Embankment.
Designed by Terry Farrell (the architect) and built by John Laing.
In 1999, it featured in the Bond film The World is Not Enough (remember when Bond's speeding boat flew out of it, and headed up the Thames).
It is by the Vauxhall Bridge. It is in a area called Vauxhall Cross, part of Vauxhall.
