The
Caves of Hercules is an archaeological cave complex located in
Cape Spartel, Morocco. Situated 14 kilometres (9
mi) west of
Tangier, the popular tourist attraction is adjacent to the summer palace of the
king of Morocco. The cave itself is partly natural and partly man-made. The man-made portion was used by
Berbers to cut stone wheels from the walls to make
millstones, resulting in the ridges visible on the walls in this photograph of the cave's interior.
