Built between 1651 and 1732, this beguiling baroque church used ingenious methods to create the illusion of grandeur at reduced cost. For example, even though the church seems to be adorned with a generous deployment of marble, all the fluted columns and pedestals are actually made from marble-toned stucco. The columns were also designed to make you think the nave is longer than its 40m (131 ft.). The facade uses larger statues on the first tier and significantly diminutive figures on the second tier to generate an illusion of imposing heights. Further intrigue can be found in the 19th-century piped organ, built by Friedrich Ladegast, one of the finest craftsmen of his time. Its construction was partially financed by an anonymous lady in black: Whenever the organ undergoes conservation work, her ghost is said to be sighted. (Her last visit was in 2002.) To fully appreciate the church, time your visit with a free organ concert. You can feel the chords reverberating on the pews as you take in both the unique architecture and the works depicting the lives of St. Stanisaw and Mary Magdalene, the church's patron saints. At press time, plans were underway to open up to the public the attic and the tunnels in the cellar, some of which reportedly lead to the Town Hall.
