of countries. Later, when Antwerp came under Protestant administration in 1581, a number of artistic treasures were once again destroyed, removed or sold. The restoration of Roman Catholic authority came in 1585 with the fall of Antwerp. In 1794 the French revolutionaries who conquered the region plundered Our Lady's Cathedral and inflicted serious damage. Around 1798, the French administration intended to demolish the building but after each blow, the cathedral was able to recover. In 1816, various important works of art were returned from Paris, including three Rubens masterpieces. Over the course of the 19th century, the church was completely restored and refurnished. Between 1965 and 1993, a complete restoration took place. Musical life At the beginning of the 15th century, the cathedral's choir started developing an active musical life, and as a result, the cathedral's importance in the history of music soon soared. Johannes Ockeghem, one of the most important composers of the 15th century, served here as a vicar-singer in 1443, and so did Jacob Obrecht between 1492 and 1497. Sixteenth-century choirmasters included Antoine Barbe, Geert van Turnhout, Séverin Cornet, and Andreas Pevernage. Organists who worked at the cathedral include Henry Bredemers (1493–1501), who went on to become a teacher to Philip the Handsome's children and the renowned English composer John Bull (1615–1628), who fled to Flanders from his home country escaping justice. From 1725 to 1731 Willem de Fesch served as Kapelmeester, followed from 1731 to 1737 by Joseph-Hector Fiocco, and from 1737 by André-Joseph Blavier. Lesser known but locally important figures, such as Jacobus Barbireau and Andreas Pevernage, also worked at the cathedral. Significant architectural details The church's one finished spire is tall, the tallest church tower in the Benelux. Charles V, Holy Roman Emperor commented that the spire should be kept under glass, and Napoleon compared the spire to Mechlin lace. The largest bell in the tower requires 16 bell ringers. The west portal features statues which include the missionary Saint Willibrord. He is thought to have spent time in Antwerp in the 7th century.
