A team of German and Peruvian archaeologists say they have discovered the oldest known monument in Peru: a 5,500-year-old ceremonial plaza near Peru's north-central coast.
Carbon dating of material from the site revealed it was built between 3500 B.C. and 3000 B.C., Peter Fuchs, a German archaeologist who headed the excavation team
The discovery is further evidence that civilization thrived in Peru at the same time as it did in what is now the Middle East and South Asia, said Ruth Shady, a prominent Peruvian archaeologist who led the team that discovered the ancient city of Caral in 2001.
German and Peruvian archeologists work at the circular 5,500-year-old sunken ceremonial plaza, built of stones and adobe, part of the Sechin Bajo archaeological complex in Casma, Andes foothills, 330 kilometers (206 miles) northwest of Lima, Feb. 2008.
