Towards the end of the 16th century, the healing springs were discovered and increasingly visited, which led to Liebwerda developing into a health resort. The Saxon Elector August I of Saxony and the Duke, Prince and General Wallenstein had the natural mineral water sent to them from the Jizera Mountains.
In the late 18th century, further spa facilities and the summer residence of Christian Phillipp Clam-Gallas, who ruled in Friedland, were established. In 1807, the Russian Grand Duchess Fjodorowna visited the spa. Seven years later, the composer, conductor and pianist Carl Maria von Weber spent a short time in Bad Liebwerda. He is said to have been inspired by the path to the Stolpich waterfall for a scene in his opera Der Freischütz. In 1840 and 1843, the Czech poet and linguist Josef Jungmann visited the health resort. From the middle of the 19th century, the town belonged to the Friedland judicial district or district.
