Cité de Carcassonne
Founded during the Gallo-Roman period, the citadel derives its reputation from its 3 kilometres (1.9 mi) long double surrounding walls interspersed by 52 towers.[1] The town has about 2,500 years of history and has been occupied in different ages by Romans, Visigoths, Saracens, and Crusaders. At the beginning of its history it was a Gaulish settlement then in the 3rd century A.D., the Romans decided to transform it into a fortified town.[2] The Roman defences were in place by 333 AD, when the town is described as a castellum. The original walls were supported by between 34 and 40 towers, spaced from 18 to 30 metres apart along the curtain wall. Each tower was semicircular in plan and about 14 metres tall. There were probably 40 main entrances to the town. Source: en.wikipedia.org/wiki/Cit%C3%A9_de_Carcassonne
