Palazzo Celsi (Via Garibaldi). Built by the noble Ascanio Celsi during the Farnese period around 1540.

It is a remarkable example of Sangallesque architecture, with its splendid and linear façade. The layout follows the block-palace style with an open courtyard, and the entrance portal is decorated with elegant rustication.

Numerous rooms are adorned with frescoes by artists of the second half of the 16th century, such as the main hall, which features depictions of the gods of Olympus and a massive fireplace, whose hood is frescoed with the image of the god Vulcan forging in his workshop.
