who discovered the ancient city of machu pichu
Machu Picchu Most archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438â€“1472). Often mistakenly referred to as the "Lost City of the Incas" (a title more accurately applied to Vilcabamba), it is the most familiar icon of Inca civilization. The Incas built the estate around 1450 but abandoned it a century later at the time of the Spanish Conquest. Although known locally, it was not known to the Spanish during the colonial period and remained unknown to the outside world until American historian Hiram Bingham brought it to international attention in 1911.
Mohenjo-daro Mohenjo-daro (Sindhi: موئن جو دڙو‎, Urdu: موئن جو دڑو‎‎, IPA: [muˑənⁱ dʑoˑ d̪əɽoˑ], Sindhi for Mound of the Dead Men;[2] English: /moʊˌhɛn.dʒoʊ ˈdɑː.roʊ/) is an archaeological site in the province of Sindh, Pakistan. Built around 2500 BCE, it was one of the largest settlements of the ancient Indus Valley civilization, and one of the world's earliest major cities, contemporaneous with the civilizations of ancient Egypt, Mesopotamia, Minoan Crete, and Norte Chico. Mohenjo-daro was abandoned in the 19th century BCE as the Indus Valley Civilization declined, and the site was not rediscovered until the 1920s. Significant excavation has since been conducted at the site of the city, which was designated an UNESCO World Heritage Site in 1980.[3] The site is currently threatened by erosion and improper restoration.[4]
