Cueva de Hércules, Roman underground structure in Toledo, Spain
The Cave of Hercules features three stone arches and ancient Roman walls constructed with opus caementicium covered in opus signinum dating from the first century.
Originally built as a water reservoir during Roman times, the structure was later converted into the San Gines church, which remained until its demolition in 1841.
Medieval tales link the cave to Hercules, describing it as a palace where treasures were sealed with locks, each added by successive local kings of Toledo.
The archaeological site welcomes visitors from Tuesday to Saturday between 12:00-14:00 and 17:00-19:00, with free admission to explore the underground chambers.
Cardinal Siliceo sent explorers into the caves in 1546, but they returned with unexplained conditions that led to their deaths, adding to the site's mysteries.
