Roman City Walls, Segovia: View of the old city center, with Roman walls and gates visible at center

An Iberian settlement preceded Roman Segobriga, settled ca. 19 BCE under the reign of Augustus. Parts of the Roman walls and the gates of S Andr\u00E9s, S Cebri\u00E1n and Santiago remain intact. Under the Moors in the 8th century, the walls enclosed a perimeter of 3 kilometers, with eighty towers and five gates. In 1985 the old city of Segovia and its Aqueduct were declared World Heritage by UNESCO.
