The interior of this triple-domed church casts a dramatic spell. The frescoes, the high and airy central dome, and the shades of rose, beige, and gray trompe-l'oeil marble on walls and arches work in concert to present a harmonious whole. The decoration followed a fire in 1709, only 30 years after the original construction. The architect and builder are not known, but it's surmised they are the same team that put up the Church of the Annunciation on Svatý Kopeček (Holy
Hill), a popular Catholic pilgrimage site just outside Olomouc.
