Millions of people travel the globe to see certain awe-inspiring and ancient landmarks that hold a special place in our world's history and have stood the test of time. From the Roman Colosseum to The Great Wall of China, these remarkable landmarks have been around for centuries, but the whopping number of tourists coming to visit them may be destroying them altogether.

It is a sad reality, but many of our beloved landmarks might not be around for that much longer. Many countries depend on tourism to boost their economy, but overtourism is a real thing and hurting places like Venice, Italy, and Dubrovnik, Croatia. Governments have even stepped in to preserve these beautiful landmarks, including The Spanish Steps in Rome, and tourists were even arrested for damaging a sacred temple at Machu Picchu in Peru.

Visiting these landmarks may never be the same again, but we need to do our best to preserve what is left of them. Here are 12 landmarks that were beautiful 10 years ago, but thanks to tourism are not anymore.

What is sadly happening to Venice, Italy, is now occurring in the city of Dubrovnik in Croatia. Overtourism is hurting the Croatian city thanks to the HBO fan-favorite Game of Thrones. Many scenes from the show, including Cersei's walk of shame and the battle of Blackwater Bay, were filmed here.
