Santa Maria Assunta Cathedral is in Parma, Italy and was built between the 11th and 12th centuries. Although the Romanesque style exterior is striking, especially the main door guarded by two stone lions, it's the treasures inside that attract most visitors.
The cathedral's highlight is the huge fresco on the inside of the dome, a sort of optical illusion depicting the Virgin Mary, by the Renaissance painter Correggio. Other features include the columns with the capitals decorated with Biblical and Mythological scenes, and the sacristy, with its marble lions.
Also worth a look is the crypt; it's been described as a stone garden with its slender columns.
