The Dreifrankenstein (German for Three Franconias Stone) is a boundary stone that marks the tripoint where the three Franconian provinces of Upper, Middle and Lower Franconia meet in southern Germany. As part of the regional reforms in 1972 the boundary marker was moved around 7 kilometres as the crow flies to the southeast. Today both points are marked by stones that are referred to as the Old and New Dreifrankenstein.
