The bodies were returned to La Paz during a ceremony at the Geneva ethnography museum.
Three mummies (two adults and a child) left Switzerland on Monday for a long return journey. They had made the outward journey, from Bolivia to Europe, at the end of the 19th century.
They were officially returned to the Bolivian Minister of Culture and Decolonization, during a ceremony at the Geneva Ethnography Museum.
This ceremony is part of a movement to return looted objects or works obtained in an opaque manner by Western institutions.
But some institutions remain opposed to it, such as the British Museum in London.
