The church of St. Mauritius in Bad Sulza fell victim to a fire in 1714. It was rebuilt in a simple baroque style and could be consecrated again in 1717. From 1722 to 1726 the west tower was added and in the latter year new bells were installed. The tower is crowned by a weather vane with the coat of arms of the Ernestine line of the Wettins and the dates 1726, 1949, 1992 as well as the initials Wilhelm Ernst Duke of Saxony. Only a few remnants remain of the various predecessor buildings, the first of which belonged to the Romanesque period as the so-called "Salt Chapel". These are most clearly visible in the originally Gothic, polygonal choir. But also some other, today closed windows and wall remains, especially in the south wall, testify to the repeated reconstructions of the church. Under the choir there is a crypt, whose practically "free-standing" vault supports the present chancel. The interior of the church is a simple hall, which is also essentially baroque. It contains three galleries, the uppermost of which is built circumferentially, the second of which carries on the west side an organ built in 1883 by Adam Eifert in Stadtilm. This originally romantic instrument was baroqueized through several alterations, especially in the 1960s and 1970s, and was restored in 1999 at a cost of over DM 100,000. In the somewhat recessed and elevated choir loft stands a Baroque pulpit by the Italian stuccoist Abondio Minetti. The freestanding mensa rises above a coping with three openings on the ground floor. In front of it stands a simple modern altar, with the baptismal font to the right. On the left side is a modern small organ, which was donated to the parish in 1976 by Sister Margarete Berlin. Behind the pulpit, two choir windows open to the east, which were made colorful by a donation from Carl Spaeter in 1908 and depict New Testament parables. On the south wall of the church is a pieta by the Bad Sulza painter Karl Hohlfeld in memory of the victims of the two world wars.

In 2018, a restoration of the interior of our church was completed. In 2005 the tower roof and the upper part of the nave were re-slated, also in 2005 we restored our crypt with donations from the Savings Bank. Through further donations we were able to purchase the two chandeliers. Through the members of the Förderverein St.Mauritius e.V. a drainage was laid around the church, the masonry was plastered. In 2008-2010 the remaining roof surfaces were newly shingled. The electrics and lighting of our church were renewed. Also this year the Förderverein St.Mauritius e.V. tries to beautify the church and to secure its preservation by voluntary work on weekends.
