Merxheim is a small town and Ortsgemeinde in the Bad Kreuznach district in Rhineland-Palatinate, western Germany. It belongs to the Verbandsgemeinde of Bad Sobernheim. The town's economy is traditionally based on wine making. The town is partnered with Merxheim, Haut-Rhin in France. The town is located around 100 km. east of the city of Luxembourg and around 90 km southwest of Frankfurt. Merxheim is located on the border of Moselle Franconian dialects and Hessian dialects.
Merxheim lies on the south bank of the Nahe between the gemstone town of Idar-Oberstein and the spa town and district seat of Bad Kreuznach.
Clockwise from the north, Merxheim's neighbours are the municipalities of Martinstein, Weiler bei Monzingen, Monzingen, Meddersheim, Kirschroth, Limbach, Heimweiler, Meckenbach, Hochstetten-Dhaun and Simmertal, all of which likewise lie within the Bad Kreuznach district.
Also belonging to Merxheim are the outlying homesteads of Gänsmühle, Kornsmühle and Weinelsmühle. German Wikipedia also lists former names for Kornsmühle (Eltgesmühle or Iltismühle) and Weinelsmühle (Franzenmühle), along with yet another outlying homestead that is not listed by the State Office for Statistics, namely Estrella, along with a former name for it (Kauzenmühle).
In the oldest document thus far found that deals with Merxheim, from 1061, Archbishop of Trier Eberhard donated the estate of Merkedesheim to Saint Simeon's Foundation in Trier. In the confirmation document from Archbishop Adalbert of Mainz (d. 1137), the name Merxheim appears for the first time. In 1350, a knight, Sir Conrad of Merxheim was mentioned. His two children, Rorich and Adelheid, shared between themselves their father's allodial holdings (lands held in fief) in Merxheim. After Rorich's death, Hunolstein and Hohenburg each took a share in the “Schloss” and village. Thus, a one-half share of Merxheim passed as an allodial and Imperially immediate holding to the House of the Vögte of Hunolstein, while the other one-half share passed to Weyrich of Hohenburg.
