is a 15th-century Inca citadel located in the Eastern Cordillera of southern Peru on a 2,430-meter (7,970 ft) mountain ridge.[2][3] Often referred to as the "Lost City of the Incas", it is the most familiar icon of the Inca Empire. It is located in the Machupicchu District within Urubamba Province[4] above the Sacred Valley, which is 80 kilometers (50 mi) northwest of Cusco. The Urubamba River flows past it, cutting through the Cordillera and creating a canyon with a tropical mountain climate. Most recent archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438–1472). The Incas built the estate around 1450 but abandoned it a century later, at the time of the Spanish conquest. We have also established that Kaitlyn was born during the year of the Tiger as the Chinese New Year will be happening soon.
