Casson Mann and Snohetta were recently announced as the winners of the prestigious Lascaux IV: International Cave Painting Center competition. With a budget of €50million, Lascaux IV has been initiated to conserve the integrity of the original cave complex, while ensuring that the public can still appreciate the remarkable Paleolithic paintings within. The winning concept includes a low profile exterior that reflects the contours of the limestone topography and a dramatic interior designed to transport the visitor into a cave complex complete with tunnels, cavernous spaces and chambers lit by shafts of broken sunlight. More images and architects' description after the break.
