I find the Theatinerkirche in Munich very appealing. Sadly this picture seems to be the only one of the first few dozens that is anywhere near the real color of the church. The amount of pictures with downright horrible white balance is astounding.
If it counts, I love the Karlsplatz Subway.
And for a little piece of local patriotism I love the Herkules at Bergpark Wilhelmshöhe, in particular juxtapositioned with Schloss Wilhelmshöhe. You can't see it on this one, but on the top of the "Oktagon" is the namegiving statue of Hercules, a pretty huge replica of the Farnese Hercules.
This one reminds me quite a bit of the Geman Pavillon at the International Exposition 1937.
