This is a 17th century "glorified Baroque mausoleum to its wealthy patron, Michael Kazimierz Pac (1624-82)," according to our guide book. Perhaps, but it was spectacular, a white interior with over 2,000 white stucco figures featuring everything from angels to demons. Well worth the drive to get there. When we arrived, one service was just ending, and within 10-15 minutes another started.
