Cappella di Santa Monica

Italian Wikipedia describes it as the chapel of the Collegio Internazionale degli Agostiniani, beside their curia generalizia. The Holy See's own published enumeration names the Collegio Internazionale S. Monica among the properties on the Janiculum that hold extraterritorial status. Under the Lateran Treaty of 11 February 1929, Italy recognises the Holy See's full ownership of this property (Art. 13; Annex II). Art. 15 states that the property, «benché facenti parte del territorio dello Stato italiano» — although forming part of the territory of the Italian State — enjoys the immunities that international law grants to the headquarters of the diplomatic agents of foreign States. It is on Italian soil and visitors are subject to Italian law. The enumeration does not address the chapel individually.
