The Southbank Centre, London is a huge, vibrant Arts centre for music, theatre, the visual arts and more. It has a rather austere exterior appearance. But search, and you will find sculpture, and other neat touches that soften the concrete walls. And you will find colour, particularly in the area around the Mexican street food restaurant Wahaca.
A neat piece of artwork shows an animal (an urban fox perhaps) attempting to scale the vertical walls.
And a corner nearby has been transformed by an attractive geometric design.
Nearby in an undercroft is the South Bank Skate Park. This has been a feature of this area for many years. This is where you will find the more familiar graffiti artists’ work.
Evidence perhaps that if there is an area for street artists to display their craft without clashing with authority, then the more visible external walls will be largely protected and will be treated with the respect they deserve.
