The underground church of San Sepolcro is situated in the historic site of the Roman forum of Milan. It was built as a private church in approximately 1030 by Rozzone (a mint master) and was then consecrated in 1036 by Archbishop Ariberto d’Intimiano. In the second half of the 16th century the quaint church was chosen by Saint Charles Borromeo as a personal place of prayer. To commemorate this, you will see a 17th century statue of the Saint inside the shrine next to the 14th century sarcophagus. The crypt reopened to the public in 2016 after a 50 year restoration project to recover the superbly decorated walls and ceilings.
