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.

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/

The Rocca dei Colonna was erected on the highest point of the acropolis in 970 AD. The initial building had a square plan with corner towers also with a square base, and housed a cylindrical tower used as a prison. Some famous people were imprisoned there, including San Berardo, bishop of the Marsi, Jacopone da Todi and Corradino di Svevia. Over the centuries, the fortress was destroyed several times; in 1482, the fortress was renovated and the event is remembered by the inscription on the turret of the small bridge "magnificus dominus Stephanus Columna readificavit civitatem cum monte et arte MCDLXXXII".
