Among the venues receiving the public this week are the Galleria Borghese in Rome, the Castello di Rivoli in Turin, and the Duomo in Florence — each with its own limits on visitor traffic, based on the building’s size and layout. Among the best bits of news is that the major Raphael exhibition at Rome’s Quirinale, which shut down only three days after opening in March, will resume from June 2 to August 30. – Artnet
