The garden at the back of Tate Modern has gone to make way for the extension and its worksite.
However, the long hoarding round the back has just been decorated with over a hundred drawings by Swedish artist Martin Karlsson.
He includes places on the Thames Path which you may have just passed such as St Saviour’s Dock and the little St Mary Overy Dock by Southwark Cathedral.
He also has a drawing of Stephen Duncan’s Old Father Thames relief found upstream on Elm Quay.
Martin calls his show London: An Imagery after Gustav Dore’s 19th-century book of drawings. It’s worth looking round the back.
