The Church of Notre-Dame in Calais is one of the principal churches in the city and it's also the oldest building in the city. Its construction began during the course of the 13th century under the direction of some renowned Flemish masters. However, visually Notre-Dame denotes the fusion of several architectural styles from different eras because its completion wasn't finished until the mid-17th century. There were a lot of proposed additions, alterations and numerous stoppages for lack of funds to continue construction. As usual, wars do not understand history or architecture and during the Second World War, this church suffered some major damage, which force the renovations process to begin, once again, for economic reasons have not been finalized.
