Archaeologists working in Peru have uncovered a 3,000-year-old sealed corridor dubbed "the condor's passageway" that likely leads to other chambers inside what was once a massive temple complex pertaining to the ancient Chavin culture. Located around 190 miles (306 km) northeast of Lima, the Chavin de Huantar archeological site is among the culture's most important centers, thriving from around 1,500-550 B.C.
