Initially it consisted of a multi-floor, square, tower, around which was built the large fortress surrounded by high walls and two circular towers. Its defensive purpose, and that of providing refuge to the local population if besieged, gained, in addition, its residential function so much so that it took on the characteristics of a different type of building, as can be seen by the large well-lit, rooms, the kitchens with large fireplaces, the internal courtyard with a fountain, whilst maintaining its orignal, primitive nature.
The Gothic entry portal, presumably among the oldest parts of the building, still has the hinges of the original closing door. It is surmounted by a niche with a male bust and the the Di Sangro emblem. Higher up, in line with the doorway, there are traces of a machicolation opening. To the left, on a portion of the restored wall, is a tower with a clock while on the right, the facade which has been rebuilt, has arches supported by corbels.
The corresponding rear elevation has two towers separated by an uneven, sloping wall. The oldest part is adjacent to the right-hand tower. The middle section with the curb stone and the part on the left date back to different, but more recent, construction phases. The structure is on three levels - the main floor had a residential function, while the ground floor and the basement were service areas. Even now there are still storerooms, wells and brick tanks for storing oil, grain and other commodities.
Internally, near the portal, there is a civilian construction while on the other side one can see the arches, now filled-in, probably belonging to a portico which perhaps led to the service rooms of the castle. We cannot accurately determine their function as even if the main floor has been preserved almost in its original form, the ground floor has definitely been altered.
