This is the best summary I could come up with:
Researchers believe the children, discovered on Monday alongside the remains of an adult, come from the Ychsma culture that developed on Peru's central coast before the Inca Empire rose to span swathes of the Andean region.
Some remains were found at the foot of a staircase on a small hill which is believed to have once hidden a temple.
Luis Takuda, an archaeologist in Lima's Rimac district, said the temple was likely built 3,500 years ago.
"The people who lived here during the Ychsma period still considered it a sacred space and therefore buried their dead here."
With a population of about 10 million, the Peruvian capital is home to some 400 archaeological ruins.
Peru's largest archaeological sites are located outside Lima in places such as Cusco, which was the capital of the Inca Empire and fell to Spanish conquistadores in the 16th century.
