Basilica is partially sealed-off but remains open to visitors.
The Vatican has sealed off part of St Peter’s Basilica after chunks of stucco fell from the ceiling during visiting time on the afternoon of 29 March.Nobody was injured in the incident which occurred at the beginning of the side nave, near the chapel housing Michelangelo's Pietà, to the right of the main entrance.
Vatican spokesman Greg Burke said work is being carried out to secure the site and the basilica remains open to the public.
The incident took place in the middle of Holy Week as the Vatican prepares for a series of papal ceremonies culminating in the Easter Sunday celebrations in St Peter’s Square.
