A modern garden table and a stone face at the window photographed inside the Hellfire Caves (also known as the West Wycombe Caves) near High Wycombe, Buckinghamshire.
The caves are a network of man-made chalk and flint caverns, excavated between 1748 and 1752, extending 500 metres underground. They were owned by Sir Francis Dashwood and came to be used for meetings of his club which later became known as the Hellfire Club.
The caves are now a tourist attraction.
