In an attractive secluded location in the country around the small town of Sant'Allesio con Vialone is a square plan castle with concentric quadrangular courtyards and a tall tower with a loggia at its apex which performed an important military lookout post role. The castle gives access to the well-known Sant'Alessio Nature Oasis set up in 1973 as a breeding centre for wild animals including non indigenous ones with the aim of returning them to their natural habitats.
