 Traces of the ancient Arab domination can be seen still today.Muslim artifacts include the "Kasr" ("Castle"), on the cape of the "Paleopolis", the district of the great mosque, the "Kalsa" ("Elected"), the emirs’ seat along the sea, the area of the "Schiavoni" ("slaves"), crossed by the "Papireto" river; and, in the western region, the "Moasker", the soldiers' quarter.However, the Arab emirate became increasingly torn by inner disputes and was a rather easy prey for the Normans, who had entered Sicily in 1061.
