A US hospital has covered a window said to feature the image of the Virgin Mary with a tarpaulin to try and reduce crowds of sightseers.
More than 25,000 visitors have flocked to see the phenomenon at Milton Hospital, Massachusetts, making access difficult for patients and ambulances.
Hospital officials are now covering the window for most of the day so patients don't have to fight through the crowds to get in.
Hospital spokeswoman Susan Schepici said the public had not heeded a request to view the form only between 5.30pm and 8.30pm. The cover is to be removed daily during those hours.
''The crowds haven't diminished,'' she told the Boston Globe. ''That's why we made the decision.''
However, some visitors remained, waiting for a burst of wind to occasionally blow the cover aside and briefly display the image. They opposed the hospital's move.
"'Morally, if this is an image of the Virgin Mother, she of all people does not deserve to be covered up,'' said Lori Benedetto, 40, who drove from Rhode Island with her mother to see the image.
Martin Miguel Joseph, 36, of Dorchester, agreed: ''For some people, this is a miracle. They should let people feel free.''
Hospital officials say the image formed when a sealant around the window ruptured and allowed heat and moisture to seep through, leaving a chemical deposit.
