This Late Baroque church has been ranked among the most beautiful in Central Europe. It's certainly the most impressive in Wrocław. The Jesuits built the church as part of the university complex in the late 17th century on the site of the Piast castle. Part of the castle structure can still be seen in the northern sacristy, the alcove at the far end of the church. The interior, painted to imitate marble and gilt, is very well preserved and most of the furnishings are original. Look up to see the fresco on the vaults; the figures are 18th-century depictions of natives from the Americas, Africa, Asia and Europe. Visitors are given an audioguide which is available in seven different languages. Donations suggested, but not required.
