Pescara is the capital city of the Province of Pescara, in the Abruzzo region of Italy. As of 1 January 2007 it was the most populated city within Abruzzo at 123,059 residents, approximately 450,000 including the surrounding metropolitan area. Located on the Adriatic coast at the mouth of the Aterno-Pescara River, the present-day municipality was formed in 1927 joining the municipalities of Pescara, the part of the city to the south of the river, and Castellamare Adriatico, the part of the city to the north of the river. The surrounding area was formed into the province of Pescara. The poet Gabriele D'Annunzio, a native of Pescara, was a major sponsor for the creation of the new city.
