It is a major tourist destination and receives almost 1.5 million visitors a year. It is designated as the Historical Capital of Peru by the Constitution of Peru.
Landing in Cusco is a great experience. City is located at the altitude of around 3,400 m so the landing strip has to be substantially longer as the air does not provide as much lift and the airplanes are landing with higher speeds.
Sacsayhuamán (also known as Saksaq Waman, Sacsahuaman or Saxahuaman) is a walled complex on the northern outskirts of the city of Cusco, the former capital of the Inca empire. The complex is as many other Inca constructions made of large polished dry-stone walls, each boulder carefully cut to fit together tightly without mortar. The site, at an altitude of 3,701 m, was added as part of the city of Cusco to the UNESCO World Heritage List in 1983.
