The Tower of Hercules
The location of Brigantium (La Coruña ), in the commercial routes of metals (gold, silver, tin etc), that linked the south of England and the commercial ports of Andalucía (south of Spain), explains the need for a lighthouse to help the ships sailing along the area find their way. Its pupose today is the same that it had in Roman time, in such a way that it is the most ancient lighthouse still working in the world.
The Tower of Hercules is located on the Atlantic coast of Gallaecia, in the ancient Brigantium, Coruna today. It is placed in the outer part of the city, between the inlets of "las Lagoas" and "Punta Herminia". Originally, it was situated on an island that was linked to the mainland throughout the years. It seems that it was built under Trajano's command, 98-117 AD.
General characteristics
The Roman building was composed of three bodies. Their height was: 8,89m the lower one, 8,87m the middle one and 12,68m the upper one. They were crowned by a crest, at the top, where fire was lit.
The main façade pointed towards the east.
The bodies, separated from the other in the inner part, were divided into four rooms communicated by doors. They were also communicated with the outer part by four doors. The communication amongst the floors was located in the outer part, probably by means of a spiral ramp. As a support was necessary to bear the weight of the ramp, an exterior wall was built. The ramp would run between the tower and the wall.
Some renovations were carried out between the 17th and 18th centuries: its exterior was covered with granite stones and the most important modification in the inner part was the building of stairs. These renovations gave the tower its present-day appearance.
