Abruzzo is a region in Italy, its western border lying less than 50 miles (80 km) due east of Rome. Abruzzo borders the region of Marche to the north, Lazio to the west and south-west, Molise to the south-east, and the Adriatic Sea to the east. Although it is geographically more of a central than southern region, ISTAT (the Italian statistical authority) considers it part of Southern Italy, a vestige of Abruzzo's historic association with the Kingdom of the Two Sicilies.
L'Aquila is both the capital city of the Abruzzo region and of the Province of L'Aquila and second largest city (pop. 73,000). L'Aquila was hit by an earthquake on 6 April 2009 which destroyed much of the city centre. The other provincial capitals are Pescara, which is Abruzzo's largest city and major port (pop. 123,000); Teramo (pop. 55,000) and Chieti (pop. 55,000). Other large municipalities in Abruzzo include Avezzano (pop.41,000), an industrial and high technology center, Vasto (population 40,636), Lanciano (population 36,000), and Sulmona (population 25,000) are three important industrial and touristic centers.
