The Castello district is the oldest in Cagliari. Being one of the historic districts, it brings together most of the attractions to visit in the city such as the Elephant Tower or the Tower of San Pancrazio, the Roman amphitheater or the botanical garden. In the past it was the residence of nobles and wealthy people from Cagliari. Over time, fortifications were built by the various populations who commanded Cagliari, making it the military, religious and civil headquarters of the city. Today it is very fascinating to walk the streets of the neighborhood along small and narrow streets and take advantage of the viewpoints to enjoy the view over the whole city.
