Rectangular in shape, richly decorated with stuccoes and allegorical representations all centred on the hunt, the Hall of Diana boasts a triple register of decorations: from the frescoed vault of Olympus, by Jan Miel Jupiter giving Diana “of the hunts the supreme empire”, the visitor's gaze can descend to seven of the ten enormous equestrian portraits of the dukes and court once present, signed by various painters in ducal service.
In the lower register are ten paintings by Jan Miel on the theme of the hunt (Hunting the Stag, the Hare, the Bear the Fox, the Wild boar; the Death of the stag; the Woods; the Gathering before the hunt; the Chase; the Curea or curing after the kill).
In the 17th century, sumptuous receptions and balls were organized in the Hall of Diana, which lies at the crossroads of Castellamonte’s perspective view that starts from the old town center to the east and continues across the hall and 1,5 km to the west into the Gardens. It also marks the middle point of the line that runs from the start of Via Maestra in the old town center of Venaria to the end of the Central Alley in the Gardens, where the Temple of Diana once stood.
