Brazilian President Michel Temer says the government is seeking funding from companies and banks to help rebuild the National Museum in Rio de Janeiro after it was destroyed by fire.
Education Minister Rossieli Soares said international help was also being sought and talks with the UN’s cultural body, Unesco, were under way.
Museum officials say almost 90% of the collection has been destroyed.
Staff have blamed the fire on years of funding cuts.
The museum housed one of the largest anthropology and natural history collections in the Americas. It included the 12,000-year-old remains of a woman known as “Luzia”.
On Monday, President Temer’s office said he had held talks with officials from major Brazilian banks and businesses to examine ways to reconstruct the museum “as soon as possible”.
Addressing reporters outside the ruined building, Mr Soares said the federal government had set aside an initial 15m reais (£2.8m; $3.6m) to rebuild the structure and restore its collection.
