What was the lost city of machu picchu?

Machu Picchu is an ancient city located in the Cusco Region of Peru, South America. Constructed by the Inca Empire in the 15th century, Machu Picchu was abandoned about 100 years later after the Spanish conquest of the Inca Empire. The city was largely unknown to the outside world until it was rediscovered by American explorer Hiram Bingham in 1911.

Machu Picchu is located at an altitude of 7,970 feet (2,430 meters) on a mountain ridge above the Urubamba River. The city is made up of about 200 stone buildings, including houses, temples, palaces, and agricultural terraces. The most famous building in Machu Picchu is the Intihuatana Stone, which is believed to have been used for astronomical observations.

Machu Picchu is one of the most popular tourist destinations in Peru. Visitors can reach the city by train from Cusco or Ollantaytambo, or by hiking along the Inca Trail. Machu Picchu is a UNESCO World Heritage Site and is considered to be one of the most important archaeological sites in the world.
