The Tower of Hercules in Spain
Roman sailors in the 1st century who saw the imposing Tower of Hercules knew they were arriving on Spanish shores. The lighthouse still stands as a monument to advanced Roman building technology and one of the world's most famous and far-reaching empires. But other history is also alive near this northwestern Spanish landmark. Near the Tower of Hercules, visitors can explore even older rock carvings, a Muslim cemetery and a sculpture park.
