Pump House Gallery the other day in Battersea Park. I forgot to take a photo of it; by the time I remembered I was half way out of the park and it was too cold to go back. I got this shot of the lake at dusk instead!
The gallery is in a tiny building overlooking the lake, some way into the park. There is some interesting history about it on their website; it used to house a pump used to circulate water around the lake and the artificial waterfalls. It now has four floors inside and is still small but perfectly formed, comprising a permanent gallery space but housing changing exhibitions. What I liked was that although the exhibition wasn't enormous the current one is very good and not at all obvious. It's titled Art, Performance & Activism in Contemporary Japan and included work from various artists and in various formats. My favourite I think was a photo about age, with a younger woman's face being cradled by the hands of older women. Definitely worth a visit.
