In 1364, Laumersheim was granted town rights by Emperor Charles IV, but then lost these rights in 1422. Later, when the place was again raised to town status, it was also fortified. These walls are no longer standing, as they were thoroughly razed in 1525 in the German Peasants' War and further demolished in 1689 by the French in the Nine Years' War (known in Germany as the "Pfälzischer Erbfolgekrieg", or War of the Palatine Succession). Only some remnants of a moated castle from the 15th century belonging to the Lords of Flersheim remain.
