Archaeologists have found the ruins of an ancient Mayan in Mexico.
The discovery was found in a construction site for a new industrial park.
The discovery was made near a place called Mérida on Mexico’s Yucatán peninsula in the South East of the country.
Experts say the site, called Xiol, has features of the Mayan Puuc style of architecture which is rare in that area.
Palaces, plazas, and pyramids form the main part of the ancient city.
Historians say the Mayan people were a civilisation that existed from around 250 AD to around 900 AD. The city is thought to have been occupied from 600 to 900 AD.
They think around 4000 people lived there.
The owners of the land say the park will still be built but the archaeological remains will be preserved.
