Down on the western side of Wiesbaden is the Neoberg City Park, and at the entrance to the park....is the Kriegerdenkmal Monument. It's a fairly big statue and can't be missed.
This was erected in 1909....a couple of years prior to WW I, and it's dedicated to the German soldiers, their victory, and efforts in German-French war of 1870/71.
You can figure it took almost thirty years for the political folks to generate up enough interest and capital to erect this. My humble guess is that noting veterans of any war in a public ceremony like this....benefits some political party and some agenda.
Generally, I'd rate the Kriegerdenkmal as one of the top three monuments in Wiesbaden to check out. About a hundred feet away from it is "Eden"....a coffee shop of sorts, that serves beer and wine. If you had a couple of hours to waste and wanted to relax.....this might be worth the effort.
