Petra is located on the slope of the Jebel al-Madhbah which is believed by some to be the biblical Mount Hor. It has been built in a basin among the mountains. The ancient city’s foundation dates back to 312 BC. It served as the capital of Nabataeans who were nomadic Arabs. The establishment of Petra allowed the Nabataeans to live in proximity to the regional trade routes and the city soon became a major trade hub of the ancient world.

Today Petra is not only one seven wonders of the world but also a UNESCO World Heritage Site. It is also listed as one of the "28 Places to See Before You Die” by the Smithsonian magazine. 2. Great Wall of China - Since 7th century BC The Great Wall of China, a global tourist hotspot, is known across the world for its uniqueness, great length, and historical value. For a number of reasons, it deserves to be one of the seven wonders of the world. The Great Wall of China is associated with thousands of years of Chinese history. A series of walls were initially built by Chinese empires and states over a period of many years, beginning as early as the 7th century BCE. These walls were then joined together to result in the Great Wall of China. UNESCO inscribed the site as a UNESCO World Heritage site in 1987. The most famous of these walls is the one built by the first Chinese Emperor, Qin Shi Huang between 220 and 206 BCE. However, only ruins of this wall remain today. The majority of the walls existing now were built during the Ming Dynasty 1368–1644). According to a survey by the Archaeological Survey, the Ming walls extend for a distance of 8,850 km. 6,259 km part of this length is the actual wall, trenches make up 359 km, and rivers and hills (natural defensive barriers) comprise 2,232 km of this distance. The Great Wall of China is made up of bricks, stones, wood, tamped earth, wood as well as some other materials. Watch towers, garrison stations, troop barracks, signaling methods further enhance the defensive characteristics of the Chinese wonder. 1.
