St. Marienkirche, Catholic church in eastern Offenbach am Main, Germany

St. Marienkirche is a neo-baroque basilica on Bieberer Straße in the Mathildenviertel, set back behind a balustraded forecourt called Paradieshof. Its 60-metre brick tower with a curved double onion dome and a sandstone facade of the Virgin of the Rosary rises above the portal. The cross-shaped interior measures 44 by 18.4 metres, with a transept 23 metres wide.

St. Marien was founded as Offenbach's second Catholic parish after St. Paul (1826), backed by Reichstag member Otto von Brentano. The building plot was bought in 1894 and a temporary church erected in 1896. In 1908 Ludwig Becker won the competition among four church architects; the foundation stone was laid on 3 September 1911 and Bishop Georg Heinrich Maria Kirstein consecrated the church on 11 August 1913.

The church serves both German and Italian-speaking Catholic communities, reflecting Offenbach's diverse population. You can see this multicultural aspect reflected in the regular services and how different groups use the space.

The church stands set back from Bieberer Straße behind a balustraded forecourt called Paradieshof, flanked by the parish and sexton's houses. The main portal faces this courtyard, and the 60-metre tower with its double onion dome rises above it. The interior is entered from the forecourt side.

Inside sits a historic Klais organ from 1914 with 30 registers and pneumatic mechanics, one of the rare surviving instruments from that era. This organ still plays during special services and concerts held at the church.
