Feast of Saints Peter and Paul — June 29

The feast of Saints Peter and Paul, one of the oldest and most solemn dates in the Christian calendar, falls on 29 June — traditionally the anniversary of both apostles’ martyrdom in Rome under Nero. St. Peter’s Basilica rises over the hill where excavations beneath the high altar have located what tradition holds is Peter’s own tomb. Two apostles, one execution year disputed by the sources themselves, and a building that has stood over the argument for seventeen centuries.
