it was to be provided with two towers of equal height. In 1521, after nearly 170 years, the new church of Our Lady was ready. The south tower reached only as far as the third-string course. During the night of 5–6 October 1533, the new church was largely gutted by fire, however Lancelot II of Ursel managed to save the building. The completion of the second tower was therefore delayed, which led to its ultimate postponement. Moreover, the church only became the cathedral of the bishopric of Antwerp in 1559 but lost this title again from 1801 to 1961, following the Concordat of 1801. During the Iconoclasm of 20 August 1566 (part of the Beeldenstorm at the start of the Eighty Years' War), Protestants destroyed a large part of the cathedral interior. The eye-witness Richard Clough, a Welsh Protestant merchant then in Antwerp, wrote that the cathedral: "looked like a hell, with above 10,000 torches burning, and such a noise as if heaven and earth had got together, with falling of images and beating down of costly works, such sort that the spoil was so great that a man could not well pass through the church. So that in fine [short], I cannot write you in x sheets of paper the strange sight I saw there, organs and all destroyed." Nicolas Sander, an English Catholic exile who was a professor of theology at Louvain, described the destruction in the church: ... these fresh followers of this new preaching threw down the graven [sculpted] and defaced the painted images, not only of Our Lady but of all others in the town. They tore the curtains, dashed in pieces the carved work of brass and stone, brake the altars, spoilt the clothes and corporesses, wrested the irons, conveyed away or brake the chalices and vestiments, pulled up the brass of the gravestones, not sparing the glass and seats which were made about the pillars of the church for men to sit in. ... the Blessed Sacrament of the altar ... they trod under their feet and (horrible it is to say!) shed their stinking piss upon it ... these false bretheren burned and rent not only all kind of Church books, but, moreover, destroyed whole libraries of books of all sciences and tongues, yea the Holy Scriptures and the ancient fathers, and tore in pieces the maps and charts of the descriptions
