a monumental statue of arminius commemorating the battle, known as the hermannsdenkmal (the "hermann monument"), was erected on the hill of grotenburg near detmold, close to the site where the most popular theory of the time placed the battle. emperor william i, the first "kaiser" of the unified german empire, dedicated the monument in 1875. in order to create a national landscape the osning hills were given the name "teutoburg forest", "see also teutonic". however, the old name survived among the local population and the part of the ridge around the ebberg (309 m) near bielefeld is still known as the osning today.
