Archbasilica of St. John Lateran
Italian cathedrals are often highly decorated and contain notable artworks; in many cases the buildings themselves are true artworks. Perhaps the best known "duomo" is the one in Florence, but other well-known cathedrals include the Milan Cathedral, Archbasilica of St. John Lateran and those of Siena, Alba, Ancona, Mantua and Parma.
