In 1030, Molsberg had its first documentary mention. From 1030, the Knights of Molsberg had their seat here on the north slope of the Eichberg at their castle. The model of the castle may still be seen today at Schloß Molsberg. In 1458, Count Philipp the Elder of Katzenelnbogen released for the 12,000 gulden by which he had raised his daughter Anna's dowry, a parcel of land to Limburg, Molsberg and Brechen from Count Reinhard of Solms and Frank of Kronberg to whom Landgrave Ludwig of Hesse had pledged it. The von Walderdorff noble family had its seat in Molsberg as of 1657.
The community's arms might heraldically be described thus: Gules a lion rampant argent armed and langued Or. These arms are demonstrably akin to the 1662 court seal. The noble lords of Molsberg had a coat of arms that was first mentioned in 1347 and showed a silver lion on a red field with a golden tongue, accompanied by a blue triple-etched gorget.
Culture and sightseeing
In the middle of the village stands the renovated former village school from 1830, which today serves as the mayor's office. Opposite stands the former seat of the Schultheiß in a more than 300-year-old timber-frame house. Schloss Molsberg was built in 1760 on the former castle's site and has at its disposal a park with trees that are under monumental protection.
Regular events
At Whitsun the traditional Pfingstkirmes is held. On Whit Monday, an open-air church service is held if the weather is fair, and this is followed by a Corpus Christi procession, in turn followed by a Frühschoppen with a concert in the square in the castle laneway under the old lindens of the Counts of Walderdorff. After prayers in the castle chapel, the kermis youth's parade begins. First at the Count's, then at the mayor's and finally in the lower village, the kermis youth dance. Here all kinds of funny anecdotes from the past year are told. The kermis festivities then move farther on to the school field. In the summer in the Counts’ castle laneway, the Kaffeehausnachmittag is held by the Wallmerod collective municipality's cultural promotion club. To the sound of waltzes, coffee and cake are served in the shade afforded by the lindens. As a general rule, the tradition-rich Molsberger Markt is held on the second Saturday in October. In 2007, however, on organizational grounds, it was moved up to 29 September.
