“Villa Gregoriana” Park, at the slopes of the acropolis, dominated by the two temples from II and III century b.C., was organized in 1834 under Pope Gregory XVI, after the diverting of the Aniene river that brought to the present order of the “great fall”.

The presence of archaeological ruins, vestiges of different periods, exceptional natural elements, caves and foreshortened views give to the park a great environmental, historical and artistic valour.

Starting from May 12th 2005, thanks to the intervention of FAI, the Villa has been opened to the public interested in enjoying its marvels.
