"Sign Post Forest Germany - Hofer Fernweh-Park" The only such place in Germany. Over 1500 signs from all over the world are displayed on the 170 poles.
When visitors and travellers come to Hof, they bring city signs, street signs and license plates from their hometowns. Many movie, music and sport stars or politicians put their signed plates, too.
