Porta Romana, Siena: Overall view

The limits on the Roman town, were the earliest known walls to the city. During the 10th and 11th centuries, the town grew to the east and later to the north, in what is now the Camollia district. Walls were built to totally surround the city, and a second set was finished by the end of the 13th century. Much of these walls still exist today. The Porta Romana, one of the old gates in the city walls of Siena, guarded the road leading to Rome. The gate was built starting in 1327.
