The town hall in the center of the historic old town was rebuilt from local travertine stones after the great town fire of 1711 in the period from 1742 to 1751.

From the medieval predecessor buildings of the town hall, the cross-vaulted stair tower and massive barrel vaults made of travertine are preserved. Bricked-up doors can be seen on the four sides of the tower, which led to the tower's circumferential gallery before 1711. A bell from 1712 is still in the tower. The main entrance on the east side is a portal decorated with gilded ornaments. Above it there is a balcony and an inscription cartouche, crowned with allegories of Fama and Justitia.

The carillon with 32 bells can play 14 different melodies and sounds daily at 12 and 18 o'clock. Five figures, about 80 cm high, appear in the triangular gable on a rigid circular segment, representing personalities from Bad Langensalza. The stucco ceiling with heraldic cartouches and niches, massive groined vaults on the first floor and coffered doors in the building have been preserved from the period furnishings. Today the town hall houses the town administration and the municipal gallery with changing art exhibitions.
