Abruzzo is a region of central Italy bordering Marche to the north, Lazio to the west and south-west, Molise to the south-east and the Adriatic Sea to the east. Until 1963 it was part of the Abruzzi e Molise region (with Molise). The term Abruzzi is an obsolete plural denomination from a time when the Bourbons administered the territory as Closer Abruzzo and Further Abruzzo.
The regional capital is L'Aquila. The region is divided into four provinces: L'Aquila (the largest), Teramo, Chieti (the most populous) and Pescara, Abruzzo's main economic centre. The four provinces are further divided into 305 municipalities. Abruzzo has a population of around 1.3 million.
