The excavations led to the discovery of seven grain pits, datable to between the late 1400 and 1500. Most were found in the area between the Spada arch and the beginning of via Roma. Three more had already been discovered, two in front of the Post Office and one on via C. Battistini, in 2012. The internal section of the pits was bell-shaped or “upside down funnel-shaped”. Excavated directly in the sandstone bedrock, they did not have a masonry-built lining, and were up to four metres deep (from the road surface), with diameters of between two and three metres. Originally, the walls were faced with straw or reed matting (as protection from the ground’s humidity) and were used to store grain, barley, oats, broad beans, almonds, chickpeas etc). Already filled at the beginning of the 1600s, they contained ceramic tablewares and common wares (plates, bowls, basins etc). Among the materials recovered was a “dump” of perfectly preserved small _albarelli_ (earthenware majolica jars), perhaps used for containing spices or medicinal preparations such as balms and powders. Investigations also took place in the “Virgina Battistini” park area. Several sections of the foundations of the cloister of the monastery of the Order of Friars Minor, built in 1607 by Carlo Felice Malatesta, were uncovered. Decorated as documented by archive sources with frescoes of the life of St. Francis of Assisi, some recovered during the work, the monastery was suppressed in 1866 and then, in 1935, turned into a school. Other interventions, along the via Cesare Battisti, led to the discovery, underneath the present road surface, of sections of two sewers built between the late 16th and the early 17th centuries and a complex underground structure. The first and earliest sewer, datable to the early 15th century, was built of stone and brick with a vaulted covering. The second was masonry-built, with a square interior section, reinforced at the sides by spandrels of cobblestones and a pitched covering built of bricks. The underground structure was entirely excavated in the sandstone bedrock and covered a surface area of 88 m2. The entrance, below the present sidewalk, led into the main room at the centre of which was a rectangular pillar supporting the vaulted ceiling. A series of corridors exited from the main room, closed by apsed niches, in which there were housings for lamps, small shelves, hooks, and holes for housing beams. Constructed before the 17th century, its original function cannot be established with any certainty. During the centuries, it was used as a cellar and shelter for the townspeople during the II World War.
