Study of alterations on Roman masonry in the Tower of Hercules

Despite its remarkable state of conservation, the Tower of Hercules, the sole surviving Roman lighthouse still in operation, exhibits notable alterations in its masonry. These changes, primarily resulting from historical influences, necessitate a thorough evaluation to inform effective preservation strategies. The study focuses on the internal core of the quadrangular structure, which retains its original Roman design, comprising four chambers across three floors. By analyzing these alterations, researchers aim to establish protocols that ensure the lighthouse's longevity while maintaining its integrity as a UNESCO World Heritage Site.
