Landgraviate of Hesse-Darmstadt
In 1736, the County of Hanau-Lichtenberg was transferred to Landgrave Louis IX of Hesse-Darmstadt, officially becoming a part of the Landgraviate of Hesse-Darmstadt. The Château de Bouxwiller became the residence of Louis IX's neglected wife Countess Caroline of Zweibrücken. During the French Revolution, the château was confiscated by the state and was pillaged in November 1793 by revolutionaries. The last remnants of the château were gone by the early 19 century. The medieval fortified city's two gates were razed in 1830.
