Ss. Andrea e Gregorio al Monte Celio

San Gregorio Magno al Celio, also known as San Gregorio al Celio or simply San Gregorio, is a church in Rome, Italy, which is part of a monastery of monks of the Camaldolese branch of the Benedictine Order. St. Augustine of Canterbury and his Benedictines were sent by Pope Gregory I to evangelize England in 597 AD. The 1,100th anniversary of the founding of their order was celebrated here at an evening Lenten Vespers service on Saturday, March 10, 2012. It was attended by Anglican and Catholic prelates, and was jointly led by Pope Benedict XVI, and Rowan Williams, Archbishop of Canterbury. It is located on the Caelian Hill, in front of the Palatine. Next to the basilica and monastery is a convent of nuns and a homeless shelter run by the order Blessed Mother Teresa of Calcutta founded, the Missionaries of Charity.

The church had its beginning as a simple oratory added to a family villa suburbana of Pope Gregory I, who converted the villa into a monastery, ca 575-80, before his election as pope (590). Saint Augustine of Canterbury was prior of the monastery before leading the Gregorian mission to the Anglo-Saxons seven years later. The community was dedicated to the Apostle Andrew. It retained its original dedication in early medieval documents, then was normally recorded after 1000 as dedicated to St. Gregory in Clivo Scauri. The term in Clivo Scauri reflected its site along the principal access road, the Clivus Scauri, which ran up the ancient slope (Latin: clivus) that rose from the valley between the Palatine Hill and the Caelian.
