St. Nicholas Church
St. Nicholas Church on Lesser Town Square is a Baroque church built for the Jesuits in two stages in the 18th century, to plans by Kryštof Dientzenhofer and his son Kilián Ignác; Anselmo Lurago finished the 79-metre belfry in 1756. Inside are a ceiling fresco in the 70-metre dome and an organ with over 4,000 pipes that Mozart played in 1787.
