On a headland at the entrance to A Coruña’s harbour, the Tower of Hercules does something unusual for an ancient monument: it still serves as a maritime signal. The Roman structure, known as Farum Brigantium, was built in the late first century or the beginning of the second century CE, according to UNESCO. It was not simply a ceremonial column. Its position above the Atlantic made it part of a practical system for navigating a difficult western edge of the Roman world.
The location explains much of the tower’s meaning. From this stretch of Galicia, ships approached a coast exposed to open-ocean weather and entered a harbour that connected the peninsula with routes toward the north. UNESCO describes the lighthouse as evidence of the Atlantic sea route linking the Mediterranean with north-western Europe. Its story therefore belongs not only to Roman architecture but also to the long history of movement along the coast, where a visible beacon could guide ships toward land and shelter.
