(CNN) — Some mistakes are hard to shake.
For over 100 years, one of the most famous archaeological sites in the world, Machu Picchu, has been known by the wrong name, according to a report published in Ñawpa Pacha: Journal of the Institute of Andean Studies.
The Incas who built the ancient city likely called it Huayna Picchu, the report said.
Huayna translates to "new or young," while Picchu means "mountain peak" in the Indigenous Quechua language, said Emily Dean, professor of anthropology at Southern Utah University in Cedar City. She was not involved in the report. Machu means "old," so we've been calling it old mountain peak, she added.
