Villa Romana del Casale (Villa Rumana dû Casali) is a large and elaborate Roman palace located about 3 km from the modern-day town of Piazza Armerina, Sicily. Through excavations archeologists have revealed one of the “richest, largest, and varied collections” of Roman mosaics in the world. Also they have revealed a rather elaborate system of water technologies including fountains, cisterns, an aqueduct, and bath facilities. This site has been designated as a UNESCO World Heritage Site.
