Casa D'Adda
The historical 19th century building owned by Società di incoraggiamento allo studio del disegno in Valsesia (owning and managing also the Picture Gallery of Varallo Sesia) has been given in loan for use for thirty years to the Nature Reserve. After its renovation and functional recovery, the building now houses the offices of the Park Keepers, the visitor center/welcome and information office, and the Congress hall.
