Among the fortifications commissioned by Pope Innocent VIII towards the end of the 15th century, in order to give solidity to papal power, the Rocca di Offida was commissioned to the Florentine architect Baccio Pontelli, his relative, who already boasted the designs of several fortresses in the brand, as in Osimo and Jesi. The project was carried out by Comancine workers and included, in addition to the construction of the fortress, also the restoration of the previous fortifications. The arilleries were commissioned in 1492, and after the fortress lost its importance, they were brought to Loreto for the defense of the Holy House, where they are still preserved. With a vaguely pentagonal plan, visible in an illustration from the end of the seventeenth century, it is characterized by two cylindrical towers, the largest of which was probably the keep, and by a square tower that protrudes slightly from the wall line. In ancient times it was also surrounded by a moat fille
