Not open to the public, the castle is only accessible on the occasion of events with extraordinary opening.
Built by the Vallaise family in the 17th century, the castle has 3 storeys flanked by 2 four-sided towers.
The internal façade opens onto the courtyard, wit a double arcade of light stone columns.
Interesting frescoes of ten fiefdoms owned by the Vallaise family can be admired in the Hall of Honour.
The park holds a hexagonal chapel dedicated to Saint Joseph, Saint Anthony and the Virgin Mary, and with a Baroque polychrome marble altar.
In past times the castle was linked by a covered gallery to the “Castello Inferiore della Costa”, now in ruins.
Acquired in 2010 from the Autonomous Region of Aosta Valley, the castle actually undergoes restoration works in order to be opened to the public.
