Thor’s Cave (also known as Thor’s House Cavern and Thyrsis’s Cave) is a natural cavern located in the Manifold Valley of the White Peak in Staffordshire, England. It is classified as a Karst cave. Located in a steep limestone crag, the cave entrance, a symmetrical arch 7.5 metres wide and 10 metres high, is prominently visible from the valley bottom, around 80 metres.
Dead Man’s Cave when the site was excavated in 1967 by George Gwynne-Griffiths was found to have Ice Age deposits, indicating that the cave was used for shelter, or as a temporary hunting camp by early man after the ice retreated.
Around 1130 AD a baker in Derby called Cornelius had a dream; a vision, in which the Virgin Mary (Mother of Jesus) told him to come here and worship God. The baker responded to God’s call and came here. He dug the cave in the hillside and lived in it for 20 years.
