On the right: City wall and towers. The old fortifications have played a vital role in protecting Girona from invaders for hundreds of years. The city wall of the old town was an important military construction built in Roman times in the 1st century BC. It was thoroughly rebuilt under the reign of Peter III the Ceremonious in the second half of the 14th century. The Roman wall was used as a foundation. At the start of the 16th century, the wall was absorbed in the city. The walled precinct lost its military value. Bit by bit, the wall was degrading, as parts were gradually altered from the inside and the outside.
