Begun by the Lutherans in 1578, the cathedral was later attributed to the Jesuits who extended the choir and added chapels. After a fire in 1723, the interior was decorated with Baroque stuccowork, which enhances the nave's brightness. Note the high-altar painting, magnificent pulpit by Christoph Rudolph, and Apotheosis of St John of Nepomuk by Joseph Fromiller. More than a dozen types of marble give beautiful tones to the side altars.
