San Martino ai Monti

San Martino ai Monti (Italian for "St Martin in the Mountains"), officially known as Santi Silvestro e Martino ai Monti ("SS Sylvester & Martin in the Mountains"), is a minor basilica in Rome, Italy, in the Rione Monti neighbourhood. It is located near the edge of the Parco del Colle Oppio, near the corner of Via Equizia and Viale del Monte Oppio, about five to six blocks south of Santa Maria Maggiore.

The current Cardinal Priest with title to the basilica is Kazimierz Nycz, the Archbishop of Warsaw. Among the previous titulars are Alfonso de la Cueva, Saint Joseph Mary Tomasi, C.R., Pope Pius XI, Blessed Alfredo Ildefonso Schuster, O.S.B., and Gianbattista Montini, later Blessed Paul VI.

The basilica was founded by Pope St. Sylvester I on a site donated by one Equitius (hence the name of Titulus Equitii) in the 4th century. At the beginning it was an oratory devoted to all the martyrs. It is known that a meeting in preparation for the Council of Nicaea was held here in 324. The current church of San Martino ai Monti dates from the Carolingian era, but remains of a 3rd-century pillared hall have been located below and adjacent to it. Some scholars have identified this earlier building with the Titulus Equitii, but according to Hugo Brandenburg, it is "most unlikely that it could have served as a place of worship for any larger community and its liturgy: The original purpose of this fairly modest hall ... was probably to serve as a storage space for commercial purposes."
