August 13, 2026, marked the 65th anniversary of the construction of the Berlin Wall.

For this reason, various installations were set up across the city.

In front of the Brandenburg Gate, for instance, there was a structure made of several elements designed to evoke the Wall.

...and then came the curious part: as long as you looked at it from the side, the wall was opaque.
But at a 90-degree angle, you could suddenly see right through it.

This effect was visible on camera, too.
