On April 18, 200-250 [sk] people attended a protest against illegal construction near Bratislava Castle, organized by Bratislava Openly [sk]. The west side of a new white house (a continuation of a historical building, photo here) had to consist of just the ground floor and a minimal attic, but the builder – architect Dušan Fischer – discovered a 2.5-meter [sk] mistake in the measurements of height above sea level and decided to use it to increase the building's height illegally (photo). Such violations are widespread in Slovakia; to set a precedent and prevent this from happening again, the protesters demanded demolishing at least part of the building.
