The Arab-Norman heritage of Palermo, Sicily.

On my last day in Palermo, the capital of Sicily, I decided to go visit the UNESCO heritage sites of the city, listed under the title "The Arab-Norman sites of Palermo, Monreale and Caflù". In fact it's not a single site but a complex of buildings located in 3 different cities, all of which dating back to the Arab and the Norman domination of the Island.
