The rows of corbeled arches ornamenting the façade, atrium walls, and the tower to the left are known as "loggia" or "arcades." These architectural elements are a common feature in Italian Renaissance buildings, providing a decorative and functional purpose. The loggia or arcade consists of a series of arches supported by columns or pilasters, creating a covered walkway or open gallery. It adds visual interest and depth to the building's exterior while also serving as a sheltered space for people to gather or traverse.
