Which New7Wonders site is also known as the 'Lost City of the Incas'?

Machu Picchu is the New7Wonders site commonly known as the “Lost City of the Incas.” The spectacular citadel sits on a mountain ridge in southern Peru, high above the Urubamba River and Sacred Valley.

The Inca likely built Machu Picchu around 1450, during the reign of emperor Pachacuti. Researchers believe it may have served as an imperial estate, religious centre, or retreat, although no contemporary written record definitively states its original purpose. Its finely fitted dry-stone walls, terraces, temples, and carefully planned water systems demonstrate sophisticated Inca engineering.

Machu Picchu was probably abandoned in the 16th century, around the time of the Spanish conquest. It was not entirely unknown locally, however. Peruvian explorer Agustín Lizárraga visited the ruins in 1902, while American explorer Hiram Bingham brought them to international attention in 1911.

The site stands about 2,430 metres above sea level and became a UNESCO World Heritage Site in 1983. It was selected as one of the New Seven Wonders of the World in 2007. The nickname can mislead readers: Machu Picchu is a citadel, not the lost Inca capital of Vilcabamba.
