As a city church St. Nicholas was built in the 13th century. For the first time the church is attested in 1266. In 1302, Bishop Siegfried of Chur allowed the demolition of the old church, in order to gain the construction site for a new and larger, as it were.
The up-and-coming municipality, which was considered a state capital until the early 15th century, made a new building in the early 15th century necessary.
Parts of the nave were built in the 14th century, but it was not completed until around 1460.
The vaulting with the ribbed vault occurred in the years around 1460 by Stefan Tobler. The graduation ceremony took place in 1465. Even the elaborately designed portals belong to this period. The organ loft was not drafted until the 17th century. From the windows belong two of the late Gothic and were originally in the Spitalkirche. The rest date from the end of the 19th century.
The tower conversion is based around 1300, the increase happened gradually. The tower end with the "Welschen Haube" - probably modeled after the parish tower in Weilheim - is set in the years 1617/1618.
The town parish church underwent extensive restoration in the years 1993 to 1999, which ultimately determines its present appearance. At the same time, the sanctuary was redesigned.
