The church of St. Nicholas is located in the Windeberg district of Mühlhausen. The church building dates back to 1802, but the church tower is older. A bell from the church in Weida/Wieda, which was demolished in 1568, was hung in the church tower in Windeberg. However, it fell victim to a fire together with the church in 1750. After this accident, two new bells with diameters of 1.01 and 0.81 m were cast for the church by Nicolaus Jonas Sorber in Erfurt in 1751. A memorial in the churchyard commemorates the victims of both world wars. 

The church is Protestant and is under the care of the Mühlhausen church district. Church services are held here regularly.
