Sathorn Unique Building "Ghost Tower," Bangkok, Thailand

Commonly known as the "Ghost Tower," the Sathorn Unique Building in Bangkok is an abandoned skyscraper that's shrouded in mystery.

The luxury high-rise was built in the 1990s, although construction was abruptly halted upon the 1997 Asian Financial Crisis. As a result, the building has fallen into decay and has become a haven for urban explorers. The inside of the tower is covered in graffiti.

While climbing to the top of the building is really dangerous, visitors can still get a glimpse inside from the ground floor of a nearby parking garage.
