The firefighters in Brazil on Sunday worked to extinguish the flames that enveloped a 200-year-old historical museum – as the president of the country called "a sad day for all Brazilians".
The National Museum of Brazil in Rio de Janeiro, also known as Rio Museu Nacional, caught fire last Sunday after the building was closed for the day, according to O Globo. What has ignited the fire was not immediately clear; the museum would have had infrastructural problems in recent years.
Sgt. Moises Torres, of the state's firefighting headquarters, said that no one knows if anyone was injured in the stake.
"Two hundred years of work, investigation and knowledge have been lost", tweeted President Michel Temer .
The museum is the oldest in Brazil. Sérgio Sá Leitão, the minister of culture of the country, told the newspaper how tragic it was to see the museum on fire and, according to a translation of his observations, he said that the fire "could certainly have been avoided".
The museum houses thousands of objects related to the history of Brazil and other countries, according to its website, and is part of the Federal University of Rio de Janeiro.
Many of his collections came from members of the royal family of Brazil, officials said.
