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'. It was constructed in the Gothic style by architects 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 cathedral is the largest Gothic church in Belgium, with its tower rising 123 meters (404 ft) over the city.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.
