The Underground in 3D

Britain has an amazing range of caves and grottoes open to the public, many of which are so old details and dates of construction are unknown. Here, I show visits to Dewstow Hidden Grotto in Monmouthshire, Dewstow Hidden Grotto, the Royston Cave, Royston Cave, and Scott’s Grotto in Ware, both in Hertfordshire, Margate Grotto in Kent and Grimes Graves in Norfolk, Grimes Graves, all in glorious 3D.
