Petra is a historical and archaeological city in the Jordanian governorate of Ma'an that is famous for its rock cut architecture and water conduits system. Established sometime around the 6th century BC as the capital city of the Nabataeans, it is a symbol of Jordan as well as its most visited tourist attraction. It lies on the slope of Mount Hor in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. Petra has been a UNESCO World Heritage Site since 1985.
The site remained unknown to the Western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt. It was described as "a rose-red city half as old as time" in a Newdigate Prize-winning poem by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage." Petra was chosen by the BBC as one of "the 40 places you have to see before you die".

Machu Picchu, “The Lost City of the Incas” and one of the current seven wonders of the World is located 130 kilometres northwest of Cusco, in the Urubamba province, at the top of a mountain of the same name and surrounded by an abyss of slightly over 400 meters that forms the Urubamba River’ canyon.
Because of its location, many visitors of this Peruvian Historic Sanctuary wonder how its old settlers moved these large blocks of stone that constitute this archaeological site and built this immense city at the top of a mountain. This mystery has generated several theories about its origin. Some people believe it is a fortress and therefore it is called “citadel” while others think that it is a religious and sacred place where the Incas worshiped their gods and made sacrifices as their main activities. According to recent investigations the most likely explanation is that Machu Picchu was built by order of Pachacutec, “the Emperor Inca”, as a resting place.
