This is one of the most noteworthy buildings in the city, topped with a monumental roof terrace. Particularly intricate is the shelved molding of the façade, decorated with stucco floral motifs alternated with seventeen metopes each engraved with a motto. Renovated several times over the centuries, it preserves a fifteenth-century Madonna of the Milk attributed to Andrea di Cagno. The decorations of eleven of the eighteen rooms present on the noble floor of the building are inspired by biblical scenes, some attributed to Marcello Leopardi, and dating back to the late eighteenth and nineteenth centuries. This is also where Pietro Ubaldi (1886-1972) was born, a world-famous philosopher and scientist, Nobel Prize candidate for literature in 1964 for his work The Great Synthesis. Today the palace is often used as a congress space.
