Landmarks is a conceptual documentation of architectural art objects on former mining dumps in the Ruhr area of Germany. As the coal was extracted from underground, inevitably the surrounding rock was also mined. This waste rock was largely unsaleable and so most of it was dumped, creating artificial hills in an otherwise flat landscape. Through a process of rewilding, and the erection of a number of art installations, some of these piles of slag and rubble have become unlikely tourist attractions. To offer a fresh perspective I decided to show the installations as mysterious objects.
