The remains of early Andean inhabitants, hunters and harpoon fishermen from more than 6500 years ago, are to be found in the department of Lima.

Lithic prehistoric projectile points of Paijan type were found at Ancón, 40 kilometres northeast of Lima in the Chillón River Valley.

[3] In 2006, a team of archeological researchers led by Robert Benfer announced their findings from a four-year excavation at Buena Vista in the Chillón River valley a few kilometres north of present-day Lima.

They had discovered a 4200-year-old observatory constructed by an early Andean civilization, a three-dimensional sculpture, unique for the time period in this region, and sophisticated carvings.

The discovery pushes back the time for the development of complex civilisation in the area and has altered scholars' understanding of Preceramic period cultures in Peru.

During this time, the Huari conquest took place, thus giving rise to Huari-style ceramics, together with a local style known as Nievería.

They conquered and absorbed the regional cultures and occupied important sites such as Pachacamac, turning it into an administrative centre.

Lately, Lunahuaná has become an adventure sports paradise, such as: Canotaje (Whitewater Rafting), Parapente & Ala Delta.
