An interesting exhibition is scheduled from 6th July to 7th September at the Wells and Mendip Museum. It features work by H.E. Balch and H. Savory and if you are interested in the early days of Mendip cave exploration you should pay a visit.
The new exhibition, Out of Time: Underground Mendip, will connect early 20th century quests for archaeological and geological knowledge with current environmental concerns. This exhibition connects the pioneering works of Herbert Balch, John Hassall, and Harry Savory, who unravelled the mysteries of Mendip caves, with new contemporary works by Ben Rivers and Emma Stibbon, aiming to inspire others to imagine the future of this subterranean world.
