Cafe tables outline pretty Hlavné nám (Main Sq), the site of numerous festival performances. Roland's Fountain , at the square's heart, is thought to have been built in 1572 as a fire hydrant of sorts. Flanking the northeast side of the square is the 1421 Old Town Hall , home to the city museum. You'll often find a musician in traditional costume playing a fujira on the steps of the Jesuit Church , on the edge of adjoining Františkánske nám.
