In the turret, one ascends via an elegant stone spiral staircase to the room of the Belvedere, equipped with a neogothic double window on each side of the octagon. Outside, the walls reveal an eclectic style typical of the neogothic, with an alternation of elements derived from Gothic, flamboyant Gothic, and Renaissance styles.
The turret conceals a mysterious cave richly articulated in several compartments, communicating with the Villa through a tunnel that has since been bricked up, while other underground pathways, now blocked, are said to have led to nearby castles (in Noale and Stigliano; and also to Castelliviero and Salzano). To complete this ensemble, a beautiful artificial lake extends beside it, which was formed by excavating material to create the elevation, and whose waters also emerge at the bottom of the cave. The underground route of about 250 meters is well-articulated in an alternation of caves, recesses (one of which is equipped with an artificial pond), galleries, tunnels, etc., and opens up outdoors, where it winds through a continuous, evocative ascent and descent along romantic paths, characterized by avenues, stairways, little bridges, leading to the lake and its wooded islands, one of which, facing the Villa, existed until the early twentieth century.
It is interesting to note how a large number of meanders, nooks, caves, and tunnels make the exploration of the path extremely varied, one noteworthy stop, certainly among the most important, is represented by a stone with chains that was meant to simulate an ancient prison of the Castle, where the condemned were tied.
