Monoliths are monuments that consist of a single solid piece, often stone.

There are natural monoliths formed by erosion, for example.

There are also older monoliths created by humans, such as rune stones.

Recently, a modern variant of monoliths has been discovered around the world.

They often consist of steel or other metal and are driven into the ground like a spear.

There are various theories as to who is behind the monolith coup.

From artists to space creatures. 

Pontus Sahlin became the one who found the first modern monolith in Sweden.

It was discovered on Wednesday evening, December 9, and disappeared without a trace on Friday morning.

- It is usually the case that monliter only stands for a few days, says Pontus Sahlin.
