Palazzaccio di Toiano is mentioned since the year four hundred, but some of its structures are certainly older. It is formed by a high stone tower with a sloping base, some buildings and a lower parts of the walls that enclose a courtyard with portal. Inside the courtyard buildings have retained much of their original character, stairways, portals, arched windows and offer visitors the illusion of a journey back in time. The most extraordinary element is a large square pillar, that supports four crossed brick vaults.
