The most ancient tavern in the world, as certified by Guinness, it was certainly already open in the year 1100 for the workmen who built the cathedral. Known as the Hostaria del Chiuchiolino (from “chiù”, drunk), its patrons included Cellini, Titian and Torquato Tasso. Ariosto mentions it in his comedy La Lena and Copernicus, who graduated from the University of Ferrara, lived in the little rooms on the first floor. During the celebrations of the 500th anniversary of the Polish astronomer’s birth, the future Pope John Paul II and Cardinal Wiszinsky, the primate of Poland, stopped by at the Osteria. Now run by the second generation of owners.
