The Cologne Cathedral is the largest in northern Europe. It contains the paintings of Stephen Lochner and is believed to hold the relics of the Wise Men of the East. Built in the Gothic style, it was begun in 1248 on the site of an older church. The nave and two spires—each of which is 515 ft (157 m) high—were included in the original plans but built later, between 1842 and 1880. For the next four years, it was the tallest structure in the world. What destroyed the original church in 1248? Discuss
