St. Marien, Catholic church in Staßfurt, Germany.

St. Marien is a Catholic church built in the neo-Gothic style to designs by architect Arnold Güldenpfennig, with a tower reaching about 60 metres. Its brickwork was largely painted white during renovations begun in 1960. The church stands at Bergstraße 5 and is listed as a monument under number 094 11210.

Construction began in 1886 as the Catholic population grew during Staßfurt's industrial expansion in the 19th century. The building has remained a landmark ever since, with updates including new bells installed in 1922.

The local community gathers here regularly for worship and celebrations that shape parish life. The interior comes alive during services, particularly when the restored organ fills the space with sound during religious observances.

The church hosts regular services and welcomes visitors throughout the week. Those interested in viewing the interior or climbing the tower should contact the parish in advance to ensure access.

The organ was installed in 1896, and its restoration began in 2018 after a severe fungal infestation was found in the organ gallery floor, which was completely demolished and rebuilt. The instrument is not documented as having been returned to service in 2020.
