Tower of Hercules.

The Tower of Hercules, a UNESCO World Heritage site in A Coruña, Spain, is one of the world's oldest active Roman lighthouses, originally built as Farum Brigantium in the late 1st century AD. Standing at 55 meters, it boasts a remarkable 34 meters of preserved Roman masonry, enhanced by an 18th-century neoclassical restoration by architect Eustaquio Giannini. The tower serves not only as a navigational beacon but also as a cultural symbol, with surrounding legends, a sculpture garden, ancient rock carvings, and a historic Muslim cemetery. Visitors can climb the tower for breathtaking views of the Atlantic and the city, while the visitor center offers insights into its rich history and enduring significance in maritime navigation.
