The Church of Reconciliation in Berlin ended up being literally trapped in no-man's-land when the wall went up in the early 60's. One door opened out onto Bernauer Strasse, which formed part of the complex border between what were becoming East and West Berlin, while the church itself all lay within East Berlin. To prevent people from escaping through the church after construction of The Wall began, they actually bricked up that door to Bernauer Strasse, as they bricked up similar doors and windows in apartment buildings up and down the street.
Eventually, as The Wall expanded to include a larger no-man's-land with vehicle traps, guard towers, and the like, the church came to be completely encased in no-man's-land, with no access to it from either East or West Berlin. Eventually it was demolished in 1985 (just 4 years before The Wall came down).
Since reunification, a small Chapel of Reconciliation has been constructed on that site. This panorama captures most of the interior of this elegant space, although doesn't indicate its height, which is several times what's visible in this image.
