The construction of the Bismarck Tower located on the "Sinnberg", a hill in the German spa town of Bad Kissingen, started in 1914 following the plans designed by architect, Wilhelm Kreis. It was projected by the local Bismarck Tower Association under the chairmanship of its founder, pharmacist Oscar Ihl. This association was in favour of Bismarck and the German Empire and competed in a certain way with the Wittelsbacher Association, which, even after the Unification of Germany, regarded the Kingdom of Bavaria to be a sovereign kingdom and built the Wittelsbacher Tower in Bad Kissingen in 1907.
