The former residential and warehouse building in "Rosenthal" in its current form dates from 1515 (d) and was built on existing, older buildings. In the course of the 10-year renovation and restoration by the city of Bad Langensalza, valuable monumental components from the 16th to 19th centuries were uncovered and preserved. This includes not only the half-timbered construction, the roof structure and the mighty ceiling beams, but also the restored components of two medieval wooden parlors, historical wall paneling with partly colored paintings and a stucco ceiling from 1693. The renovation of the house enabled the establishment and opening of the Thuringian Pharmacy Museum in the "Haus Rosenthal" with adjacent Pharmacy garden in May 2014.
The Thuringian Pharmacy Museum can be visited from Wednesday to Sunday from 1 p.m. to 5 p.m. Guided tours, lectures and Other Events.
