Monte Cassino is a rocky hill about 130 kilometres (81 mi) southeast of Rome, Italy, 2 kilometres (1.2 mi) to the west of the town of Cassino and 520 m (1,706.04 ft) altitude. Site of the Roman town of Casinum, it is best known for its historic abbey. St. Benedict of Nursia established his first monastery, the source of the BenedictineOrder, here around 529.
The hilltop sanctuary was the site of the Battle of Monte Cassino in 1944, where the building was destroyed by Allied bombing and rebuilt after the war. The site has been visited many times by the Popes and other senior clergy, including Pope Benedict XVI in May 2009.
Since the reforms of the Second Vatican Council the monastery is one of the few remaining territorial abbeys within theCatholic Church. On 23 October 2014, Pope Francis applied the norms of the motu proprio Ecclesia Catholica (Paul VI, 1976)[1] to the Abbey. This act removed from its jurisdiction all 53 parishes and reduced its territory to the Abbey itself - while retaining its status as a Territorial Abbey. The former territory of the Abbey, except the land on which the Abbey Church and monastery sit, was transferred to the local diocese of Sora-Cassino-Aquino-Pontecorvo.
