Just under the surface of Nottingham, England, there’s hidden world ripe for exploration, from a 14th century dungeon that once reputedly held a king prisoner to a 19th century butchery. Not just anyone can get to most of these 450+ sandstone caves, many of which are located under Nottingham Castle, and they’ve never even been accurately mapped – until cutting-edge laser technology made these incredible 3D scans possible. The Nottingham Caves Survey has already recorded the shape and surface details of 35 caves, layering them with above-ground photos to give us an unprecedented and surprisingly artistic view.
