As museums begin to reopen, many are requiring visitors to book tickets in advance, wear masks, use hand sanitizer upon entering or undergo temperature checks, according to Fortune. In Munich, the Bavarian State Painting Collections’ museums are limiting the number of visitors to one person per roughly 215 square feet, reports CNN’s Karina Tsui. At the Giacometti Institute in Paris, meanwhile, just ten people are allowed in every ten minutes, and public bathrooms remain closed. – Smithsonian
