Palermo, the capital of Sicily is over 2 700 years old and as such is renowned for its history, culture, gastronomy and architecture; particularly its interesting array of Norman buildings. A visit to the city would not be complete without checking out Palermo Cathedral, the city's main church and San Giovanni deli Eremiti near the Palazzo die Normanni, notable for its brilliant Arab-influenced red domes. The Palazzo for its part is one of the most beautiful Italian palaces and certainly worth a visit, as is the Teatro Massimo that opened in 1897 and to date is one of Europe's largest theaters. Other highlights include the Quatro Canti, located at the crossing of the ancient main roads that divide the town into its quarters, and the city walls, many pieces of which remain till today.
