Investigation under way after fire

Roberto Leher, rector of the university, said it was well known that the building was vulnerable to fire and in need of extensive repairs. In fact, the institution had recently secured approval for nearly $5 million for a planned renovation, including an upgrade of the fire-prevention system, but the money had not yet been disbursed.

On Monday, officials promised $2.4 million to shore up the building and promised to rebuild the museum.

"Those saying that the museum will be rebuilt are not telling the truth," said Luiz Philippe de Orleans e Braganca, an heir to Brazil's last emperor. "The building could be rebuilt, but the collection will never again be rebuilt. Two hundred years, workers, researchers, professors that dedicated in body and soul (to the museum) ... the work of their life burned due to the negligence of the Brazilian state."

The museum, whose main building was once home to the royal family, had extensive paleontological, anthropological and biological specimens. It also contained a 12,000-year-old skull called Luzia that was among the oldest fossils ever found in the Americas. It held an Egyptian mummy and the largest meteorite ever discovered in Brazil one of the few objects that officials could confirm had survived.

Cristiana Serejo, a vice-director of the museum, told the G1 news portal that maybe around 10 percent of the collection had survived.
