Carnglaze Caverns, located near St Neot in Liskeard, Cornwall, England, is comprised of three man-made caverns originally formed as part of a slate quarry in the Loveny Valley. The first cavern, known as the Rum Store, was used by the Royal Navy during the Second World War for rum storage and later converted into an auditorium. The lowest cavern features an underground lake, famously pictured on the cover of Echo & the Bunnymen's 'Ocean Rain'. The venue has hosted performances by artists such as Fish, Fairport Convention, Embrace, and British Sea Power.
