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.
Marina Silva, a former environment minister and candidate in October's presidential elections said the fire was like "a lobotomy of the Brazilian memory".
