It is likely that the Festari had the elegant palace erected on a pre-existing structure, which included a beautiful garden at the bottom that has also been restored and is now connected to the site of the adjacent "Domenico Dal Lago" Paleontological and Archaeological Civic Museum. In addition to the museum, the palace houses the Informagiovani office and the Municipal Police Headquarters.
Currently, in the central body of the building, there are two conference rooms set up on the first floor and on the second floor is the Conference Hall, which is equipped with a control room with videoconferencing equipment.
Palazzo Festari also houses the Fondazione Palazzo Festari. A foundation that has as its main purpose to provide knowledge, tools, and strategies useful for developing opportunities and paths for economic, social, and cultural growth in the valley and high Vicenza area. In addition to it, the Palace hosts, on the ground floor, the Municipal Police, Informagiovani, and the ProValdagno headquarters.
Palazzo Festari also features a prestigious Conference Hall with a capacity of 150 seats and equipped with a control room with videoconferencing equipment. The “Galleria dei Nani”, in the bright courtyard of the palace, serves as an exhibition space granted upon request by the Municipal Administration for events of public artistic, cultural, or social interest. The premises of the palace also host the “Paleontological Museum D. Dal Lago,” which displays a rich collection of fossils found in the valley in 26 showcases and offers free visits with the accompaniment of a guide.
