The article talks about the discovery of the lost city of Upanao, a pre-Inca civilization in Peru. The city was discovered by a team of archaeologists led by Benedictine monk Brother Eusebio Francesco Chini, also known as Father Siculo, in the 16th century. The city was not rediscovered until 2019 by a team of archaeologists from the University of Warsaw.
The team used a combination of satellite imagery, drone photography, and ground-based surveys to locate the city. The city covers an area of about 60 hectares and was occupied from the 12th to the 15th century. The city was made up of several large plazas, residential areas, and religious buildings.
The team found several artifacts, including pottery, stone tools, and textiles. They also found the remains of a large temple complex dedicated to the worship of the sun. The temple complex includes several large stone platforms and a sunken court.
The discovery of the city is significant because it provides new insights into the development of pre-Inca civilizations in the region. The city also provides evidence of the extensive trade networks that existed in the region during this time period. The city of Upanao is a unique and important archaeological site, and the team plans to continue their research in the coming years.
