The Domus Sanctae Marthae is a building adjacent to St. Peter's Basilica in Vatican City. Completed in 1996, during the pontificate of Pope John Paul II, it is named after Martha of Bethany, who was a sibling to Mary and Lazarus of Bethany. The building functions as a guest house for clergy having business with the Holy See, and as the temporary residence of members of the College of Cardinals while participating in a papal conclave to elect a new pope.
