Outside (and inside) Stazione Termini, Rome's main railway station, stand sections of an eleven-kilometre-long circuit of defensive walls, which were built almost two and a half thousand years ago.
Traditionally attributed to Servius Tullius, sixth king (c. 575- c. 535 BCE) of Rome, the walls were actually built in the early 4th century BCE, during the Roman Republic, in response to the sack of the city by the Gauls in 390.
10 m (33 ft) high in places, and 3.6 m (12 ft) thick at the base, the walls were built of large blocks of tuff.
