Passageways in the Rock

 Located at Las Fuentes del Marqués (Marquis' Springs) in Caravaca de la Cruz.

This is a cave artificially excavated into the rock, dating back to the Islamic period. Above the cave, there is a series of channels and basins, possibly associated with some form of artisanal industry. These may have been linked to leather tanning and dyeing, or to the distillation of alcohols and aromatic plants, activities that require an abundant supply of running water, are typically situated outside of cities, and rely on raw materials that were once plentiful in the area.
