The name "Rothenburg ob der Tauber" means, in German, "Red fortress above the Tauber". This is so because the town is located on a plateau overlooking the Tauber river. As to the name "Rothenburg", some say it comes from the German words Rot (Red) and Burg(burgh, medieval fortified town), referring to the red colour of the roofs of the houses which overlook the river.
