Forte Altavilla di Ancona, 19th-century fort in Pietralacroce district, Ancona, Italy.
This military fortification sits on elevated terrain overlooking the Adriatic coast, featuring pentagonal earthworks, casemates, underground galleries, and original defensive structures from the 1860s construction period.
Built between 1860-1866 by architects Giuseppe Morando and Biagio Debenedictis, the fort served as part of Ancona's second defensive line during Italian unification, costing approximately 791,000 lire for the new kingdom.
Recognized as Italian national heritage, the fort represents post-unification military architecture and hosts cultural events, exhibitions, and educational activities that preserve the memory of 19th-century defensive systems.
Located at via di Pietralacroce 86, the fort is accessible by public transport or car following directions toward Portonovo, with parking available nearby and seasonal bus services connecting to the city center.
The fort maintains its original drawbridge, caponiere structures, and Carnot walls visible from the moat, while underground chambers remain closed to preserve their historical integrity and visitor safety.
