Museums that have opened in Vienna include the Albertina, the Leopold Museum and the KHM Museum of Fine Arts. In Brussels, a number of museums also opened in mid-May, according to Patrick Bontinck, CEO of Visit Brussels. Visitors must wear masks and observe social distancing, and to reinforce the standards, the museum website offers cartoons explaining the new rules. In Denmark, museums reopened June 8 with similar measures, and Norway's Munch Museum will reopen in Oslo on June 15, with limited capacity. Meanwhile, some smaller French museums and cultural venues already reopened, including the Giacometti Institute, which reopened May 15, with online advance ticket purchase required.
