Red Church ~ part 2 by aukjejetty
No, this is not the same red church, but it is on the same hill. This one looked like a Catholic church. Later on I looked on the map where these both churches are. They can be found a little south-east of the main railway station (Hauptbahnhof) along the Michaelsbergstrasse.
