Castello di Fumone is a historic fortress located in the province of Frosinone, Italy, notable for its strategic position atop a conical hill 800 meters above sea level. Originally constructed in the 10th century, the castle served as a military defensive outpost and a high-security papal prison. It is globally recognized for holding Pope Celestine V captive for ten months until his death in 1296. The site features a 3,500-square-meter hanging garden, which is recorded as the highest in Europe. The architecture incorporates Romanesque foundations, medieval defensive walls, and Renaissance residential renovations. Private ownership by the Longhi de Paolis family allows for tours of the inner chambers, armory, and preserved archival rooms. The fortress was never successfully conquered throughout its centuries of operation. The site remains a primary historical witness to the power struggles between the Papacy and the Roman nobility.
