The festival and spa town of Bad Hersfeld 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, which have taken place each year since 1951 at the monastery ruins. These themselves are said to be Europe's biggest Romanesque church ruin.
In 1967, the town hosted the seventh Hessentag state festival.
