The site preserves a collection of large carved stone grotesques, monsters, and allegorical figures set within a wooded garden, along with a tilted small house, all original sixteenth century Mannerist carvings rather than later additions, though vegetation and weathering have altered their setting over time. It is privately owned, currently by the Bettini family, and is not a state monument. The park is open to the public on a ticketed basis.
