Monreale’s cathedral complex was inscribed on the UNESCO World Heritage List as one of the ten sites of the “Arab-Norman Palermo and the Cathedral Churches of Cefalú and Monreale” circuit in 2015. Architecture and art, and - above all - the magnificent mosaics and decorations in both the cathedral and the cloister make Monreale a “must” on every discerning Sicily traveler’s to-do list.
