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.
Dholavira The site was discovered in 1967-1968 by J. P. Joshi ex. D.G. of A.S.I. and is the fifth largest of eight major Harappan sites. It has been under excavation since 1990 by the Archaeological Survey of India, which opines that "Dholavira has indeed added new dimensions to personality of Indus Valley Civilisation."[7] The other major Harappan sites discovered so far are: Harappa, Mohenjo-daro, Ganeriwala, Rakhigarhi, Kalibangan, Rupnagar and Lothal.
