Berlin (dpa / bb) - The former "Entenkeller" in Berlin-Frohnau caught fire on Sunday evening.
The roof structure is burning, this is visible from afar, said a fire department spokesman.
80 emergency services are on site or are still on the way.
At first there was no further information.
Over the years, the building on the B96 - once a popular excursion destination - has housed a hotel, a pizzeria, a bar, a disco and a pub.
It has not been used since 2012 and is empty.
