Fountain Bigger than a Church

After a pleasant day in the Black Forest, including a trip to see Germany's largest waterfall (Triberg Waterfalls - an overall drop of 163 metres over 7 cascades),
took a quick detour into Baden Baden.
As the name suggests, it's a spa town.

Was going to blip the Triberg waterfall, but I've done a couple of waterfalls already
(see High Force and Near Loch Assynt)
decided to pick another water related blip of this fountain.
