The White City was discovered deep in the jungles of Honduras.
Officials said excavation that began Wednesday have so far unearthed about five dozen stone and ceramic fragments and other artefacts. The pieces appear to date to between 1,000 and 1,500AD, Institute Director Virgilio Paredes said.
The dig is being carried out by archaeologists from Honduras’ Institute of Anthropology and Colorado State University.
The most striking piece discovered appears to be a ceremonial seat or throne made of stone, carved with the figure of a jaguar.
The city’s name is believed to be derived from the white limestone rock in the area, or a cult purported dedicated to a monkey god.
The area is inhabited by the Pech and Payas indigenous groups, who long spoke of such a site. The first written reference came in 1544, in a document written by Spanish Bishop Cristobal de Pedraza.
U.S. adventurer Theodore Morde claimed to have discovered “The Lost City of the Monkey God” in 1940, but didn’t reveal the location.
The rumoured site had supposedly been located and lost between the 1500s and the 1800s. Researchers detected the current excavation site in 2012.
