About
Carnglaze Caverns is a unique venue set within Cornwall's only underground slate mine, featuring three spacious caverns and an underground lake. The Rum Store cavern, once used by the Royal Navy for rum storage during World War II, now serves as an auditorium licensed for up to 400 guests. The site also includes 8 acres of ancient oak woodland with a themed woodland walk. Open to the public since 1973, it offers an atmospheric setting for events beneath the earth's surface.
