If it looks like a school, is located like a school and stands next to a new school, it probably is a school. This bexomes extremely evident, if you read the text on the wall, which says school.
Built in the late 1950’s or early 1960’s, this building served as the primary school of a village all the way until 2021, when a new school was built next to it.
The wing closest to the camera are former teacher apartments, which have since found use as a kindergarten. The wing straight ahead is the school gym. The wing invisible between them is the classroom wing.
Closed for around a year when I took this picture, I seemed unable to find any info on what they plan to do with the buildings.
I can only guess. And I have a bad feeling about this.
