This is the Wasserturm in Mannheim, Germany.
This is one of the first places we visited when we got here last November. We took the Strassenbahn (street car) into town with all 5 children(what were we thinking). The Fountain was empty, but the kids watched some of the local children riding their bikes around in it.I am just grateful that we didn't lose any of them on the Strassenbahn.
