Cloister of Santa Maria La Nuova
The lovely Benedictine cloister of the abbey adjacent to the Duomo was built at the same time as the church but enlarged in the 14th century. The enclosure is surrounded by 216 intricately carved double columns, every other one decorated in a unique glass mosaic pattern. Afterward, don't forget to walk behind the cloister to the belvedere, with stunning panoramic views over the Conca d'Oro (Golden Conch) plain toward Palermo. If you wish to visit, reserve a tour online at least a week in advance.
