Why come
Civitella del Tronto sits at 589 meters on a long limestone ridge above the Tronto valley, on the old border between the Papal States and the Kingdom of the Two Sicilies. The Fortezza that runs the spine of the town is the largest fortress in Italy and the second-largest in Europe after the Hohensalzburg at Salzburg, 500 meters long, 45 meters wide, 25,000 square meters of walls, courtyards, and casemates. It is the reason people come.
In 1860 and 1861 the Piedmontese army laid siege to it for five months. The Bourbon garrison capitulated on 20 March 1861, three days after the Kingdom of Italy had already been proclaimed in Turin. Civitella was the last Bourbon flag still flying.
The centro storico below the fortress narrows into the Ruetta, said to be one of the narrowest streets in Italy at 38 centimeters at its tightest. The town sits inside the Gran Sasso and Monti della Laga National Park.
