The urban layout and the medieval dwellings that remain in Provins are an outstanding example of an architectural ensemble built specially to fulfill these functions. The city is also known for its well-preserved defense system, which was built for the protection of the fairs. Criterion (iv): Provins preserves to a high degree the architecture and urban layout that characterize these great medieval fair towns. The urban plan of the medieval town is well preserved, as are a large part of the historic buildings, canals and the water management system. AuthenticityDue to its economic decline, but also to the persistence of its urban functions, the medieval fairs town of Provins remains relatively intact to this day.
