In 1354 Emperor Charles IV made it one of the grouping of ten towns called the Décapole that survived annexation by France under Louis XIV in 1678 and was extinguished with the French Revolution. On 25 January 1677 a great fire destroyed many houses and the Hôtel de Ville; its replacement dates from 1741 to 1752. Many early structures were spared: the Maison du Sel (1448), under its Alsatian pitched roof, was the first hospital of the town. There are many 15th- and 16th-century timber-frame houses, and parts of the walls and gateways of the town. The "Maison de Stanislas" was the retreat of Stanisław Leszczyński, ex-king of Poland, from 1719 to 1725, when the formal request arrived on 3 April 1725 asking for the hand of his daughter in marriage to Louis XV. The First Battle of Wissembourg took place near the town in 1793.
