History In 1211, Heusenstamm had its first documentary mention in an Eppstein fief book in which Gottfried of Eppstein documented that he held the castle and village of Huselstam in fief from the Empire and that he had further bestowed these holdings upon Eberhard Waro von Hagen-Heusenstamm. The place was later called Husinstam and, beginning in the 15th century, Heussenstain. About the middle of the 12th century, Eberhard Waro von Hagen-Heusenstamm had a moated castle built here. From the Middle Ages until 1819, Heusenstamm and Rembrücken belonged to the Biebermark, an area held in common with several other villages. After the Lords of Eppstein died out, their position was filled by the new feudal lords, the Counts of Königstein, and later, beginning in 1581, by the Elector of Mainz. In 1545, Sebastian von Heusenstamm was chosen Archbishop-Elector of Mainz. In 1560 Eberhard von Heusenstamm gave leave to introduce Protestantism, but Roman Catholicism was reintroduced in 1607. After the Lords of Heusenstamm died out in 1616, the castle and the lordship passed to the family's Austrian sideline, who then leased the place to the Frankfurt patrician Stephan von Cronstetten. During the Thirty Years' War, the village and the castle were almost utterly destroyed.
