2,500 Years- The Great Wall Of China, Beijing 

Coming in at number one in the ranking for the longest time of construction is the Great Wall of China, taking approximately 2,500 years to complete. Ordered to be built by Emperor Qin Shi Huang as a wall of defence, construction of the wall started in the 7th century and was completed by 1878. This breathtaking structure stretches 21,000 miles across 15 Chinese provinces and has become one of the most visited tourist attractions in the world with over 10 million visitors each year.

The general admission price to visit the wall starts at 20 yuan, but children under 1.2 metres can enter for free. For those activity seekers, you can book a guided hiking trail which typically takes around 5 days to complete, or if you want to travel in style through the variety of transport options to get across the wall like a cable car or down the toboggan slide, this will come at an additional cost.
