There are tons of abandoned places and buildings all over the world. It is weird to think about the fact that sometimes buildings just go untouched for decades. From small houses to farms to airports to mansions, anywhere can become abandoned under certain circumstances. There are also abandoned cars, planes, trains, and so much more to discover.

It is unusual to see these normally high-traffic places so empty and quiet. They raise questions pertaining to how the building got to be abandoned, what used to go on when it was not abandoned, and what might come of it in the future. It is hard to say why some places go abandoned, but the mystery is part of what makes it cool.
