A good friend was teaching Architecture at the University of London, and sat on the board at the Tate Modern Art Museum in London.. He would spend hours talking about that building. It was an old Power Station that they rehabed on the bank of the Thames River, and just breathtaking in person, not to mention some of the finest collections of art in the world.
Notice the size of the people in the second picture to get an idea of how huge the place is...
