The city was plundered and damaged by fires during the Thirty Years' War (c. 1632). Fires again destroyed large parts of the city in 1711, including complete destruction of the city hall. The city hall was rebuilt between 1742-1752.
Langensalza is something of a tourist spot, with picturesque ruins of a medieval castle, and sulphur baths nearby.
The sulphur baths were discovered in 1811, and opened to the public as a curative bath in 1812. A new version of the public sulphur bath was opened in 1928. Salt and mineral water springs were discovered in 1996, which prompted the opening of many new curative facilities.
