LIMA, Peru — Although the top tourist destination in Peru is the ancient Inca citadel of Machu Picchu, high in the Andes Mountains, the capital Lima also holds a treasure trove of ancient ruins — so many, in fact, that authorities can't take care of them all.
The city is home to more than 400 known pyramids, temples and burial sites, many of which predate the Incas and and are known in Spanish as "huacas." They sit next to modern shopping centers, hotels and highways or rise up in the middle of neighborhoods in this city of 11 million people. Meanwhile, archaeologists keep digging up new sites.
