I've mentioned before that the South Bank is one of my favourite areas of London. Although I am not a big gallery goer (can I say that?) I do like the Tate Modern - basically because you can wander in and out as you wish and, for the most part, it's free. I have always been a big fan of the exhibitions/installations in the turbine hall. There's something about the sheer size of the art that is appealing. The turbine hall allows for some huge installtions or just a lot of space in which to interact (or lie on the floor as we did for the weather project). They are celebrating their fourth anniversary this year and BBC News has some great pictures from some of those bigger exhibitions.
