It’s hard to imagine famous landmarks like the Taj Mahal or the Kremlin being destroyed by negligence when they’re such important tourism hotspots. Except it already happened to Notre Dame.

Many landmarks are forgotten when governments change, populations migrate, or funds run out. In this way, architectural marvels and monuments to the past are often turned into unrecognizable piles of rubble.

Tourists aren’t deterred by the risk of injury that comes with visiting sites that are half-toppled, rusted over, or even radioactive. Stealing a glimpse of a once beautiful landmark as it inches into nonexistence is an amazing moment. There might not be many more opportunities in a few years.

Here are 20 disturbing photos of these neglected landmarks that can be enjoyed in the safety of your home.
