Brazil’s National Museum in Rio de Janeiro, opened in 1818 and home to over 20 million artifacts has been completely destroyed by fire. The three-story museum was closed when the fire quickly consumed the building. Founded by John VI, the King of Brazil and Portugal, the museum celebrated its 200th anniversary earlier this year. The cause of the fire is currently unknown. Brazil's President Michel Temer called it a tragic day for Brazil. "200 years of work and research and knowledge are lost."
