Hercules, Tower ofprobably the only ancient Roman lighthouse still in use, located 1.5 miles (2.4 km) outside in the city of La A Coruña (Corunna), Spain, on a peninsula in Corunna Coruña Bay. A Phoenician tower may have occupied the site originally, but the present structure, 185 feet (56.8 mmetres) tall, is considered a Roman work dating from or at least remodeled during the reign of Trajan (AD 98–117).
