Frankfurt (Oder), Radolfzell. The construction work on the former Ostquell Brewery in Frankfurt (Oder) has been successfully completed this summer. The “Old Brewery”, which has been in the ownership of EuroNatur since 2003, had been in a poor state of repair. The renovation work, which began in 2018, could only be carried out in the summer months so as not to disturb the hibernating bats. Recently, over 1,200 bats, mainly greater mouse-eareds, have been spending the coldest time of the year within the old walls.

Holes in the roof were repaired and new beams put in to keep the roof construction stable in the coming years. In some rooms in the maze of cellars the walls were sealed to prevent frost penetration. Whilst bats like it cool, minus temperatures can mean an abrupt death for these insect-eating mammals. “We are very happy with the construction work carried out and delighted that we have been able to preserve the former Ostquell Brewery as a bat hotel,” said EuroNatur project leader Sandra Wigger.

From 26th-28th October 2021, EuroNatur, the Association for Landscape Conservation of the Middle Oder and the Liga Ochrony Przyrody are organising an international bat conference on the theme “Protection of bat populations – threats, problems, practices, solutions”. The focus of the conference is on exchange of information about large man-made sites for bats, such as industrial buildings, churches, bunkers etc.. There will also be a discussion on the measures to be taken in the “Frankfurt (Oder) Old Brewery”. The conference will take place online. Those who are interested can register by 25th October 2021 via this link:  euronatur.org/batconference21


Background information:

  • With an area of only just 0.25 hectares, the building in the former Ostquell Brewery in the middle of Frankfurt (Oder) may be Brandenburg’s smallest nature reserve, but it is one of the most important hibernation sites for bats in Eastern Germany. The “Old Brewery” provides excellent conditions for the hibernating bats: the cellars are cool but free from frost and provide the high humidity needed by the bats. In addition, it is virtually free of any disturbance. EuroNatur has owned the former Ostquell Brewery since 2003 and it is looked after by the Association for Landscape Conservation of the Middle Oder.
