Aside from the excellent cultural facility's the Barbican Centre has to offer, ranging from theatre, art, music and dance. The space outside the Centre holds personal value in its ability to evoke nostalgia of the Emerald City, in the slightly disturbing film 'Return to Oz'. I enjoy residing by the fountains, where I draw, read books and feed ducks.
I love swimming and I love being outside. London is great if your into both these things. I swim at London Fields Lido which is heated all year round. Its best in the winter when the steam rises from the water and if your lucky its snowing a little on your head. If your brave you can also go for the unheated option of the Serpentine or Hampstead Ponds.
