Enna (SICILIA) Enna lies in the heart of Sicily, in a panoramic setting on a stretch of high ground in the region of the Erei hills, and, at 931 m. above sea level, is the highest provincial chief town in Italy. Once a Siculi settlement, in pre-Roman times it was held by the Greeks, Syracusans and Carthaginians. Though a municipium at the time of the Roman Empire, it was of no great importance, and its history was that of the region: Greek domination then Byzantine, followed by that of the Arabs and Normans (11th century), as part of the Kingdom of Sicily. Its monuments include: Castello di Lombardia, built by Frederick II of Swabia over previous constructions: 6 of its 22 towers are still standing (interesting interiors); the Duomo, of 13th century origins, rebuilt in the 16th century, richly frescoed; the church of S. Francesco d'Assisi (14th century). The principal town in one of the most impoverished provinces of Italy, Enna has an economy based principally on the service industries, employment in the public sector being of particular importance; the industrial sector is underdeveloped, apart from traditional mining activities (sulphur, potash) and now in difficulty. Events: Festa di Maria Santissima della Visitazione (2nd July), summer events at the Castello di Lombardia. Famous People: Giuseppe Alessi (man of letters, 1774-1837), Napoleone Colajanni (politician, 1847-1921). Cultural Institutions: State Archives, Library, Museo Alessi (numismatics section, archaeological exhibits, ceramics, paintings). In the Province: Calascibetta (of urban and environmental interest), Nicosia (cathedral, agricultural centre), Barrafranca (sulphur extraction), Piazza Armerina (Roman villa Casale, agricultural centre), Lake Pergusa (car racing).
