TERRANOVA, or Terranuova, a seaport town of Sicily, on a hill at the mouth of the Terranova, in the province of Caltanisetta, and 411/2 miles east-south-east from Girgenti. It contains a castle and several large churches, but has little to interest the traveller. Though the harbour is poor, there is a considerable trade in corn, wine, fruit, sulphur, and soda. Cloth is manufactured to a small extent. The population of the town in 1881 was 16,440, that of the commune 17,173. In and near Terranova are the remains of the ancient Gela (q.v.). The modern town owes its origin to the emperor Frederick II.
