The spa and town museum was opened in October 2008. In 2023, the museum was redesigned. The museum is located in one of the oldest and most beautiful town houses in the town, which has been extensively renovated in accordance with the monument protection regulations, in a central location on the market square, right next to the spa and tourist information office. In seven exhibition rooms, it mainly displays material evidence of the eventful development of Lausigk or Bad Lausick into a spa and bathing resort, as well as the town's history.
Since the 12th century, Lausick has had a prominent regional importance in administrative, ecclesiastical and at times military terms, which is described in detail and clearly. Of particular interest, however, is how the healing waters were discovered and used and how Lausick became a renowned spa and bathing resort.
The museum is equipped with an audiovisual and a listening station, which convey both the historical spa operations and the brilliance of the sound of the Silbermann-Trampeli organ in Lausick's St. Kilian's Church.
