Cave of Hercules

It was covered with a barrel vault, realized in ashlar, and displayed the aspect of a great tank to the open sky, with an overflow at the edge.

The first half of the wall, made in Roman concrete and covered with opus signinum, is preserved, and overlooks San Ginés alley.

A facade was built in opus quadratum of seven rows of ashlars of varying size, which is attached to the northeast lateral wall of the hydraulic structure of the first phase.

This mosque followed a structure similar to others of the city, being a small oratory with practically square plant, four interior columns and nine vaults or domes.

At the end of this Late medieval epoch, or the beginning of the Early modern age, a series of changes were made, such as the creation of five individual chapels.
