The museum dedicated to the condottiero (military leader) is located in the basement of the structure, where the stables and cannon foundry were once situated. The exhibition path employs modern multimedia tools, showcasing documents, images, photographic reproductions, and videos. The central theme of the exhibition revolves around the figure of Bartolomeo and his victorious career, revisiting the most significant stages of his political and cultural activities in Pordenone. He was the Lord of Pordenone and established an Academy there in 1508. The museum reconstructs his most important military enterprises. Emphasis is given to the battles of Agnadello (1509) and Marignano (1515), with two spaces dedicated to them, featuring interactive tools such as 2D and 3D virtual simulation systems. Another noteworthy room is the one that used to house the stables, still preserving its original medieval vaults, serving as another example of medieval architecture. The Museum of Peasant Civilization is also located in the underground areas, once used as a stable and warehouse. Its purpose is to preserve and enhance the knowledge of the rural cultural heritage of this region. The displayed collection is the result of in-depth research into the economic and social life of the area between the 19th and 20th centuries. It includes all the tools and objects used in field work and domestic life: tools for cultivating and harvesting wheat, grapes, olives, and hemp, equipment for fishing, caring for courtyard animals and livestock, as well as tools used in various prevalent artisanal activities of that time. This museum represents an important testimony to the customs and traditions linked to Alviano's agricultural past and its people. Within the splendid Renaissance porticoed courtyard, other rooms of great interest are present. Starting from the ticket office room, three interconnected chambers allow visitors to admire the only original frescoes of that era preserved in the entire castle. These artworks tell us much about Bartolomeo's personal history, recounting family marriages and the resulting strategic alliances with important families of the time, such as the Orsini and Baglioni, and even the Medici. The frescoes are attributed to Giovanni Antonio de Sacchis, known as Il Pordenone, considered the greatest Friulian painter of the 16th century. He stopped in Alviano during some trips to Rome, partly due to his friendship with Bartolomeo's family. The Castle also houses a small chapel overlooking the porticoed courtyard, dedicated to Saint Francis. Inside, frescoes attributed to Giuseppe Bastiani, a painter active between Umbria and the Marche towards the end of the 16th century, depict episodes and miracles from the life of Saint Francis. Of particular interest is the scene of the "Miracle of the Swallows," which took place in Alviano in the spring of 1212. Section: the clay houses The clay houses represent a distinctive form of housing in Alviano, primarily found in the area occupied by the calanchi (eroded clay formations). These constructions, dating back to the 19th century, have become a symbol of the poorest peasant civilization and the close relationship between humans and the resources of the land. They were built using humble materials found locally by the farmers. In addition to their modest dwellings in the village, the farmers constructed these huts to seek shelter in the fields during summer nights. Due to their distance from main communication routes and the absence of water sources, Alviano's inhabitants were compelled to utilize the few resources that the land provided: clay, rainwater, straw, and wood for the door and window frames, as well as for the roof beams. These clay houses typically consisted of one or two rooms, sparsely furnished with the dowries of young brides. Over time, they were often expanded with small additions to accommodate growing families. Not all the owners of these houses lived there throughout the year; especially during winter, many preferred to return to their homes within the village. Even today, some of these structures are used by locals for various purposes, such as housing livestock or storing tools for fieldwork. Others have been recently restored, providing a tranquil and extremely panoramic spot to stop and perhaps enjoy a pleasant picnic. The clay houses are a precious treasure to be carefully preserved, both because they are a unique feature of this area and because they embody the peasant civilization and the connection between rural history and the local territory. Due to their value as bearers of ancient traditions and ways of life, the clay houses are protected by the superintendent to ensure their safeguarding in all aspects, thus continuing to bear witness to the peasant civilization of the past.
