monastery (1727). The Passionists came in 1758 and restored it in 1783, using the materials of the temple of Jupiter, as found and raised by Henry Benedict Stuart, Duke of York, bishop of Frascati. During this period there were guests in the monastery: the king Francis II of Naples in 1865 and Pope Pius IX in 1867. The "contemplative-missionaries" abandoned the monastery in 1889. In 1890 the structure was converted to a hotel that entertained national and international personalities, among others: Umberto II of Italy, Massimo d'Azeglio, Luigi Pirandello, Armando Diaz (who sojourned in Rocca di Papa and was remembered with a commemorative headstone mail in the residence on De Rossi palace) and the King Edward VIII with his wife Wallis Simpson. From 1942 the hotel was used as military base for radio communications by the German Wehrmacht. On June 3, 1944, soldiers of 142nd Regiment-36th Infantry Division (United States) ("Texas" Division), attacked and captured the military site—with 20 enemy soldiers killed and 30 prisoners taken.
