Berliner Dom/Berlin cathedral, Berlin, Germany
Berlin cathedral was built from 1893-1905, on a site where two other churches had been since 1536. The church has never been a cathedral in the literal sense of the word, since it has never been the site of a bishop. The church, build in exuberant Neo-Renaissance style, was much larger than it's two predecessors and was considered a protestant counterpart of the St. Peter's basilica in Vatican city.
The beautiful and impressive dome of the cathedral. It's not the original dome however, as this was destroyed due to allied bombs in WWII. The reconstructed dome is a simplified version of the original design. You can see the original design here and the war damaged state of the cathedral here.
