The Domus Sanctae Marthae (Latin for Saint Martha's House; in Italian, Casa Santa Marta) is a building adjacent to St. Peter's Basilica in Vatican City. Completed in 1996, during the reign of Pope John Paul II, it is named after Saint Martha the hospitable, who was a sibling to Saints Mary and Lazarus of Bethany. The building presently functions as a guest house for various clergy having business with the Holy See, and as the hotel residence of the members of the College of Cardinals when they are participating in a Papal Conclave to elect a new Pope.
