Rocca di Offagna

Rocca di Offagna is a fortress built on a tuff rock formation, featuring thick brick walls with approximately 50 bombard positions designed for artillery placement. The structure includes a five-story central keep and continuous defensive walkways that once protected the surrounding territory.

The Maritime Republic of Ancona built this fortress between 1454 and 1456 to defend its territory against the rival city of Osimo. Its construction reflects the political tensions and military needs of the Adriatic region during the Renaissance period.

The fortress holds a weapons collection developed through partnerships with the Academy of Oplology and Military History of Ancona and San Marino State Museums. Visitors can observe how military equipment and armor from different periods shaped the region's defensive practices and daily life.

The fortress is accessible year-round and allows visitors to walk through secret passages, historical rooms, and explore the interior layout. Panoramic views from the keep's terrace provide orientation and show how the surrounding landscape influenced the site's defensive design.

The castellan's residence on the third floor contained the fortress's only chimney, reflecting his elevated status within the structure. Access to the keep was intentionally positioned on the fourth floor to enhance the building's defensive strength.
