This garden can be found on the roof of the Queen Elizabeth Hall at the Southbank Centre.
The 1,200 square metre garden, which was created in 2011 as part of the 60th anniversary of the 1951 Festival of Britain celebrations, was developed in partnership with the Eden Project.
It is maintained by volunteers from Grounded Ecotherapy, a group which offers people dealing with issues like homelessness and addiction help through horticulture.
The Garden features more than 200 wild native plants as well as a lawn, paths and paving – and stunning views across the river. There’s also a cafe and bar.
