Part of that day included a guided walk around the Southbank complex's garden-themed 'Discover Our Neighbourhood'. We walked through the lovely roof gardens above the Queen Elizabeth Hall and the individually curated freestanding allotments along the river and had a quick peek in at the Beano's 75th birthday exhibition.
I have yet to revisit all of these (preferably on a sunny day so that I can make use of the beer garden!) and I hope to do so later this week or next. I am also keen to check out a lot of the interesting free exhibitions, especially Lambeth Treasures, plus many other things, too numerous to mention here.
See here for all there is to offer.... but hurry... most of these events end on 8th September.
