One of Latin America's most famous archeological sites figures in our Geo Quiz.
A century ago, an American scholar led an expedition that collected artifacts and ancient bones from a mountaintop high in the Andes.
50,000 pieces in all — including human skeletons — were taken from the Incan city of Machu Picchu.
They've been kept at Yale University since then.
Now, they're being returned to Peru. A repatriation ceremony was held Thursday in a Peruvian city where the bones and artifacts will now be kept.
The city we want you to name was once the cultural capital of the Incan Empire.
The answer is Cuzco. A collection of artifacts and bones were taken from Machu Picchu 100 years ago by Yale scholar Hiram Bingham. Yale University is now in the process of returning the items. The BBC's Mattia Cabitza has the story.
