According to the police, the roof of a swimming pool in Schwedt "completely collapsed" on Sunday - a few days before the planned reopening of the renovated hall.
A police spokesman said in the evening that an area of around 50 by 70 meters was affected, and damage was caused by millions.
Nobody got hurt.
The “Aquarium” in the city in Brandenburg is currently closed due to renovation work.
The reopening was planned for Thursday (July 15th).
"We were still lucky, if that had happened on Thursday there would have been deaths," the spokesman said.
Fortunately, at the time of the collapse, no construction work was in progress, the spokesman said.
Only two people who work in the swimming pool's gastronomy and offer take-away sales were therefore on site - they were unharmed.
According to the police spokesman, the renovation affected the swimming pool, not the roof.
After the collapse, there was no longer any swimming area to be seen, and the renovation work was probably completely obsolete.
The cause is still completely unclear, it said.
The building is locked for the time being.
The investigation into the cause of the collapse continues on Monday.
