The Old Town in the Fulda valley has an oval shape and an area of some 40 ha.From west to east it stretches some 960 m and from south to north some 570 m.
This can still clearly be seen today, as where the town moat once led around the town there is today a ringroad that leads traffic around it.
Besides the main town – also called Bad Hersfeld – the town also has the outlying centres of Allmershausen, Asbach, Beiershausen, Eichhof, Heenes, Hohe Luft, Johannesberg, Kathus, Kohlhausen, Petersberg and Sorga.
The nearest cities are Kassel, 52 km to the north, Gießen, 79 km to the southwest, Fulda, 36 km to the south and Eisenach, 45 km to the east.
Through Bad Hersfeld runs the Deutsche Fachwerkstraße (“German Timber Frame Road”), a holiday road that showcases many of Germany’s timber-frame houses and buildings.
The town lies in the Hersfeld Basin formed here by the forks of the Fulda and the Haune. Furthermore, the Geisbach and the Solz empty into the Fulda in the municipal area.
In the southwest lie the Vogelsberg Mountains, in the northwest the Knüllgebirge and in the northeast the Seulingswald (ranges, the latter visible in the background of this image).
The town’s lowest point, at 195 m above sea level, is to be found in the area where the Solz empties into the Fulda, whereas the highest point within town limits is the Laxberg in the Knüllgebirge, at 408 m above sea level.
The town can be said to belong both to Northern Hesse (Nordhessen) and Eastern Hesse (Osthessen).
The festival and spa town of Bad Hersfeld (Bad is "spa" in German; the Old High German name of the city was Herolfisfeld) is the district seat of the Hersfeld-Rotenburg district in northeastern Hesse, Germany, roughly 50 km southeast of Kassel.
Bad Hersfeld is known countrywide above all for the Bad Hersfelder Festspiele (festival), which have taken place each year since 1951 at the monastery ruins.
The Old Town stands on an alluvial or fluvial fan made of gravel and pebbles, which were washed up between Fulda and Geisbach.
