Archaeologists in Peru say they have discovered a temple at the ancient site of El Paraiso, near the capital, Lima.
Entry to the rectangular structure, estimated to be up to 5,000 years old, was via a narrow passageway, they say.
At its center, the archaeologists from Peru's Ministry of Culture found a hearth which they believe was used to burn ceremonial offerings.
With 10 ruins, El Paraiso is one of the biggest archaeological sites in central Peru.
The archaeologists found the structure, measuring 6.82m by 8.04m (22ft by 26ft), in the right wing of the main pyramid.
