La Rocca Pia is an imposing 15th-century fortress located in the very historic center of Tivoli, in Lazio. Built starting in July 1461 by order of Pope Pius II Piccolomini (from whom it takes its name), the fortress was created with the dual objective of militarily controlling the strategic access routes to the city and reaffirming papal authority over the citizenry after long periods of unrest and internal clashes, particularly between the Guelphs and Ghibellines factions and the powerful Colonna and Orsini families. The project, completed under the pontificate of Pope Alexander VI, is traditionally attributed by the only historical source (Vasari) to Filarete and his disciples.

From Tivoli's Gregorian Bridge, you can enjoy a spectacular view of the Aniene Gorge, the natural canyon carved by the river, and the Roman Acropolis with its ancient temples. Looking toward the "old" part, you can admire the houses clinging to the rock and the Temple of the Sibyl, which turns golden at sunset. Here's what you can see from the bridge: The Tivoli Gorge: The Aniene River flowing deep within, part of the evocative Villa Gregoriana Park. Roman Temples: The acropolis with the Temple of the Sibyl and the Temple of Vesta, symbols of ancient "Tibur." Historical Panorama: The medieval and historic houses overlooking the chasm, offering a glimpse of old Tivoli. The Great Waterfall: With the surrounding landscape of the gorge. The bridge itself, built in the 19th century by Pope Gregory XVI, is an iconic vantage point located at the entrance to the historic center.

Tivoli's Rocca Pia, an imposing Renaissance fortress located in the city center, was built by Pope Pius II Piccolomini starting in 1461 to defend the city and control the population. The structure is characterized by four large circular towers of varying heights, connected by high crenellated walls. Over the course of its history, the Rocca has alternated defensive functions with those of a papal barracks and, for a long time, a prison until 1960. It is currently a tourist attraction located near Piazza Garibaldi and the Bleso amphitheater. WEBSITE: https://visittivoli.it/sito-turistico/rocca-pia/

A small shelter, behind which is an underground cistern. A picnic area with barbecue grills is a great place to relax.
