The outer opening to this cave may be seen from the bottom of the Avon Gorge, as a gaping hole some 250 feet up a sheer cliff. It has, of course, been fenced in for the security of visitors. However, the more usual way of entering the cave is through the Observatory where a descending mined passage with steps leads into a natural chamber.

This cave has a very long and interesting history. It was first mentioned as being a chapel in the year A.D. 305 and excavations have revealed that it has been both a holy place and a place of refuge.

Although the cave is in limestone, there are few formations in the natural passages.

Visitors are admitted without a guide, and only the artificial part of the cave is illuminated. This is a charming little cave, and provides excellent views over the Avon Gorge, the river and surrounding countryside. Only the brave however, stand on the grid at the end and gaze down the 250 feet into the gorge below.
