Yale University has promised to return thousands of archaeological pieces taken from Machu Picchu nearly a century ago, Peru's president has said.
The relics from the 15th Century Inca citadel have been the focus of a bitter dispute lasting more than seven years.
Peru says the artefacts were loaned in 1911 but never returned. It filed a lawsuit against the university in 2008.
The agreement comes after a concerted media campaign by Peruvian President Alan Garcia and his government.
Marches fronted by ministers and the president himself were staged in Lima and Cuzco. Mr Garcia even appealed directly to his US counterpart, Barack Obama, to intervene.
Earlier this month, the Metropolitan Museum of Art in New York returned to Egypt 19 artefacts found in the tomb of King Tutankhamun.
