Longwood Swallet, Limestone cave in Mendip Hills, Somerset, England
Longwood Swallet extends through 1.65 kilometers of Carboniferous Limestone formations, reaching depths of 175 meters below the surface point.
Students from Sidcot School discovered this underground system in September 1944, adding it to Somerset's network of documented caves.
The Charterhouse Caving Company maintains strict access control to protect geological features and ensure responsible exploration of the cave system.
A concrete block entrance with warning signs alerts visitors about frequent flooding caused by nearby water extraction operations.
The cave forms part of the Cheddar Complex Site of Special Scientific Interest, connecting to August Hole through limestone passages.
