I often pass by this church when I'm in the train going home. I never got the chance to take a photo of it until last week. Too bad I can only come this near as we were in a hurry to go to the city center. - The kids were hungry lol.
The Breitenfelder Kirche/Church lies between the belts Florianigasse and Feldgasse - a busy area very near the University. From the above perspective you wouldn't really see a triangle no? But from below I know you would. :)
For photohunt's triangle theme.
