Formerly a Roman Catholic Church and Bernadine convent, it was built according to the Vilnius Baroque style. Laid in 1642 and completed in the 18th century, the cathedral is a valuable monument of Old Minsk. Six columns divide the inner room into three naves. The mid nave, traditional for basilica-type temples, is considerably wider and higher than the lateral ones. The iconostasis has a number of marvelous icons including the Our Lady wonder-making icon that miraculously appeared on the Svisloch bank back in 1500.
