Today we visited Karlsruhe, one of the big German cities in the Baden-Württemberg state. Before going there I read that there has been some speculation about this city being used as a model for Washington, D.C. (since both cities have a centre from which the streets radiate). I couldn't stop thinking about this point when we were walking in the city center. When we passed by the Rondellplatz, we observed this obelisk that might, in fact, be a model for the American one. Probably this city is very nice during the summer, but today we realized spring hasn't come yet to Karlsruhe because it was rainy, grey, and cold... brrrr.
