Torre de Hercules, Spain
The Torre de Hercules, or Tower of Hercules, was built by the Romans above La Coruña harbor in northwestern Spain in the 1st century, AD. The lighthouse is believed to be the only Greco-Roman lighthouse to retain its architectural integrity.
Originally called the Farum Brigantium, the tower sits on a 187-foot-high rock and stands an additional 180 feet high. The tower underwent restoration in the 18th century, and today visitors can also tour a sculpture garden, see rock carvings from the Iron Age and explore a Muslim cemetery.
