First called Fabricio by the Romans, it became Ferraia when the port was used for exporting iron- "ferro". Cosimo I de’Medici had fortifications built around the harbour here in the 1500s. Fort Stella, Fort Falcone and the tower Linguella are joined by these walls. These fortifications became Napoleon’s prison. From the beginning of the 20th century until WWII, the metallurgic industry was prosperous but suffered much damage due to bombing.
