Kraków's most picturesque street, and an essential part of any tourist itinerary. The cobbled alley is lined with superb examples of Renaissance and Baroque architecture, and many of the facades feature colourful murals and passageways leading to quiet courtyards. At number 9 is the former residence of 18th century patriot Hugo Kołłątaj, number 17 is the grand 14th century Bishop Ciołek Palace (now a museum of religious art), number 19 next door was once the residence of the future Pope John Paul II (today it houses the Archidiocesan Museum), and at the very end, number 25, lies the former royal bathhouse nowadays better known as 'Dom Długosza.' One popular tale surrounding the bathhouse claims that the future Queen Jadwiga, concerned about rumours that Lithuanians had gigantic genitals, sent one of her servants to spy on the manhood of Lithuanian Grand Duke Jagiełło - her husband-to-be. Her fears appear to have been allayed and the couple later got married.
