This transition caused the obliteration of the original Visconti structure, marking a significant shift in the Citadel's history.

The surviving parts of the ancient fortified nucleus of La Crotta, including the imposing Adalberto tower, were recovered.

The Hospitio Magnum building, the arched portico, and the tower at the entrance (Torre della Campanella) featuring the Citadel Clock were also restored.

Further restorations from 1985 to 1988 uncovered the remains of the Salt Tower and other parts of the complex, ensuring the preservation of the historical site.
