documents let us think that the Delfinale Tower of Oulx had a role more linked to the presence of royal officials on territory that real military purposes. We have no information on the historical period in which the importance of the tower began to be less neither on the era in which it was definitively abandoned; it was however already registered as ruin in a consegnamento of 1735. The precarious state of the building induced the cav. Luigi Des Ambrois of Nevache, minister of Carlo Alberto native Oulx, to request the tower in emphyteusis perpetual, in order to provide for a restoration useful to preserve the ruins, without altering its characteristics. The request was accepted by the Municipality.
After the death of Des Ambrois tower passed to their heirs who only in recent years have submitted formal renunciation of their rights by returning the product to the common; since 1978 it has been subjected to the constraint by the Soprintendenza for Architectural and Environmental Heritage of Piedmont. Today the building is recupretao and restored and is fascinating exhibition space for exhibitions and events.
