Digital scans of about 300 objects mean modern techniques could be used to build replicas.
Last month, Brazil's 200-year-old national museum burned down in Rio de Janeiro.
Much of its collection of 20 million artefacts was lost in a single night.
But now there's a plan for a new museum to rise from its ashes.
Experts will sort through the rubble to save and repair what they can.
And modern technology means there's hope for some of artefacts, as Arabella Munro explains.
