The architecture is vast and somehow reminiscent of the SouthBank Centre. But the space is a plenty and light pour through all floors. Amazing views from the top. I have put a few pictures on Facebook and no doubt you will find better one on the Tate's website. www.Tate.org.uk. It opens to the public on Friday and please make a point of going to visit it. you will enjoy it.
This last picture was a performance that made me think of the dancers by Matisse.
