The majority of Blackgang's Victorian coastal development, along with the chine itself, was obliterated by landslides and coastal erosion over the 20th century, part of a general pattern of erosion affecting the Undercliff area. A major landslide severed the old road between Blackgang and Niton in 1928, and subsequent ones destroyed most of the remaining road segment and adjoining houses, as well as the Sandrock Spring in 1978. Currently Blackgang comprises the amusement park (whose buildings incorporate some of the village's former residential houses such as the Blackgang Hotel and Five Rocks), a tearoom, and a few other houses.
