History and description
Construction of the Palazzo dei Priori started in 1460 and 50 years later it was inaugurated by the Priori (a kind of municipal council). It actually consists of two pre-existing buildings connected by an arch, the Palazzo del Comune (as the Palazzo dei Priori is also known as) and the Palazzo degli Uffici (or Palazzo del Podestà).
The corridor connecting these two buildings serves as a Pinacotheque.
The central portico giving access to the courtyard of the palazzo has never been changed in the course the centuries. The upper floor, on the other hand, has undergone several renovations. The facade facing the Piazza del Plebiscito is preceded by a portico consisting of nine arches supported by columns.
The coat of arms with the oak tree and papal tiara on the loggia is the one of Sixtus IV della Rovere, Pope from 1471 to 1484. His name is also on the architrave above the first-floor windows and above the interior doors, explained by the fact that he also contributed to some renovations.
A new wing was constructed towards th end of the 17th century.
Courtyard
In the courtyard of the building are a number of benches of the stone type peperino. The fountain, made in 1626 to a design by Caparozzi, is characterized by two lions climbing a palm tree. Lids of Etruscan sarcophagi, recognizable by the images of semi-reclining figures, are also on display. From this garden one has a beautiful panoramic view of the Valle Faul. The right side of the courtyard has a 5 arch portico. The loggia above the entrance was built in 1632.
A wide staircase leads to the top floor.

Cappella del Magistrato
The Cappella del Magistrato is located on the right above the stairs and was created by Domenico del Fattore and Filippo Artesanta. Construction began towards the end of the 16th century. In 1631 the chapel was completed and one could admire the frescoes with “Events from the Life of the Virgin” painted by Filippo Caparozzi and Marzio Ganassino. The plasterwork and the altar were made by Spinzio.
