Städtische Badeanstalt Neuwied, Heritage bathhouse in central Neuwied, Germany

Städtische Badeanstalt Neuwied is a bathhouse built in 1908 to designs by Cologne architect Wilhelm Knoppe on the site of the old Catholic church in the upper Marktstraße. Its swimming hall is broken up by niches and galleries, and the building also held showers and tub baths. It has served as an office complex since 1985 and is a protected monument.

The bathhouse was approved in 1904 and opened on 22 June 1908, built on the site of Neuwied's old Catholic church, which was demolished after the Matthiaskirche was completed. Julius Remy donated 70,000 of the estimated 160,000 marks, but costs reached 271,000 marks. It closed in 1985 due to a leaking pool and was renovated as a protected monument from 1997 to 1999.

The bath women, city employees nicknamed "Quartalswäscher", scrubbed bathers with soap before they entered the tubs. The 1909-founded Neuwieder Schwimmverein 09 trained here, and its member Hermann Heibel competed at the 1936 Olympics. After the war, the women's section became independent and known as the "Nixen" for its water ballet.

The building no longer functions as a public swimming facility but operates as an office and business space today. Visitors can appreciate its architectural details from the exterior while walking through central Neuwied.

The bathhouse replaced the old Catholic church of the upper Marktstraße, demolished after the Matthiaskirche was completed in 1904. The city approved the new bath on 11 May 1904; costs were estimated at 160,000 marks, of which Julius Remy donated 70,000, but the final bill reached 271,000 marks.
