The Cathedral of Our Lady () is a Roman Catholic cathedral in Antwerp, Belgium. Today's see of the Diocese of Antwerp started in 1352 and, although the first stage of construction was ended in 1521, has never been 'completed'. In Gothic style, its architects were Jan and Pieter Appelmans. It contains a number of significant works by the Baroque painter Peter Paul Rubens, as well as paintings by artists such as Otto van Veen, Jacob de Backer and Marten de Vos. The belfry of the cathedral is included in the Belfries of Belgium and France entry in the list of UNESCO World Heritage Sites. History Before 1124 The first Christian missionaries arrived in the 7th century. The first parish church dedicated to Saint Peter and Saint Paul was constructed in the current Sint Michielsstraat. After the Viking raids in 836, the church was damaged and restored, and subsequently dedicated to Saint Michael. In the 10th century, a group of 12 secular canons were connected to this church. They would dedicate all of their time to the Liturgy of the Hours, and mainly opposed the beliefs of the established Roman Catholic Church. Upon hearing of their dissent behavior, the bishop of the Roman Catholic Archdiocese of Cambrai (to which Antwerp belonged at the time) then sent Norbert of Xanten to discipline them. In 1124, Norbert of Xanten convinces 4 of the secular canons to start a norbertine abbey and thus the parish church becomes a monastery church, known as St. Michael's Abbey. The 8 other secular canons prefer to keep their freedom and move to a different location, a chapel dedicated to Our Lady, the Virgin Mary. This chapel becomes Antwerp's new parish church, and is located between the Saint Michael residential area, and an older settlement around the area of Het Steen. Our Lady's church Becoming more popular, the chapel is demolished and replaced by a much bigger romanesque church. The three-aisled nave corresponded in width to the cathedral's current central aisle, the inner and partly the middle aisles. The cloverleaf-shaped eastern section with a full aisle had a width of no less than 42 m. In 1294, the church gets a novum opus extension, indicating the first signs of gothic architecture. Our Lady's cathedral and damage In 1352, construction was begun on a new Our Lady's church which would become the largest Gothic church in Belgium. In the beginning,
