Machu Picchu, the legendary 'Lost City of
the Incas', is without a doubt the most important tourist attraction in Peru
and one of the world's most impressive archaeological sites
Built by the Incas on the summit of "Machu
Picchu" (Old Peak), overlooking the deep canyon of the Urubamba river in a
semi-tropical area about 44 mi (70 km) northwest of Cuzco at 8,000 feet
above sea level.
It sits on a mountain site of extraordinary
beauty, in the middle of a tropical mountain forest, Machu Picchu was
probably the most amazing urban creation of the Inca Empire at its height,
with its giant walls, terraces and ramps, which appear as though they have
been cut naturally in the continuous rock escarpments.
