The Hayward Gallery in Southbank center has held my favourite exhibitions in London and each time they are extremely well curated. Definitely a place to visit !
It's such an iconic building and it's always a joy to be anywhere near it. It just dominates the landscape around it. Ever since I first saw the cover of Pink Floyd's Animals I've loved it and I still do. There are always reports in the news for plans for developers to spend billions on refurbishing it. I'd genuinely prefer it to remain as it is rather than see it being turned it into a massive shopping centre full of chain stores. The thought of it being turned into some kind of Westfield full of people on Facebook on their laptops in a Starbucks fills me with rage.
An unassuming glass door on an otherwise plain facade hides a cavernous space, with high ceilings and huge sliding partitioned walls producing excellent exhibitions in a space you'll want to go back to.
