Watch How These 12 Amazing Landmarks Get Ruined By Tourists

Teotihuacán, Mexico

One of Mexico’s most magnificent and mysterious ancient cities, Teotihuacán is best known for its two huge pyramids: the Pyramid of the Sun and the Pyramid of the Moon. These mighty temples, an easy day trip from Mexico City, are the country’s most-visited archaeological site, attracting millions of visitors every year.

Unsurprisingly, it can be swarmed by vendors as well, keen to sell their wares to the visiting crowds. The site gets especially hectic during the spring and fall equinoxes when thousands descend on the site, believing the structures have a special energy.

With great crowds of people seen clambering up the pyramids’ steps there are concerns over damage to the ancient monuments.
