7m long in various Purbeck marbles and Welsh Slate. This large public art installation just outside the South Transept of St Paul’s Cathedral makes good use of various different types of natural stone to illustrate the change in alignment between the Old, pre-fire, Cathedral and the present one built by Sir Christopher Wren. The intention was to create something informative, easy to understand and also very attractive. The stones used come from the Isle of Purbeck in Dorset and have very rich shell content, producing a beautiful and lively surface. The outlines were created through the use of waterjet technology, which enabled the stone to be inset in a manner which would either be impossible or prohibitively expensive if done by hand. The explanatory inscription around the border was hand carved into the stone.
