Brazil’s oldest and most important historical and scientific museum has been consumed by fire, and much of its archive of 20 million (yes! 20 million) items is believed to have been destroyed. The fire at Rio de Janeiro’s 200-year-old National Museum began after it closed to the public on Sunday and raged into the night. There were no reports of injuries, but the loss to Brazilian science, history and culture was incalculable, two of its vice-directors said. “It was the biggest natural history museum in Latin America. We have invaluable collections. Collections that are over 100 years old,” Cristiana Serejo, one of the museum’s vice directors, told the G1 news site. Brazil’s president, Michel Temer, who has presided over cuts to science and education as part of a wider austerity drive, called the losses “incalculable”. “Today is a tragic day for the museology of our country,” he tweeted. “Two hundred years of work research and knowledge were lost.” It wasn’t immediately clear how the fire began, but it is said that the museum didn’t have enough funds for maintenance of hydrants.
