The Late Gothic "Malteserkapelle" arose as a church of a settlement of the Sovereign Military Order of Malta/Knights Hospitaller. The quire was built in 1456 and the nave completed in 1465. The chapel's quire stands taller than the nave. The building's exterior is framed by stepped buttresses and windows with fish-bladder tracery. After the Reformation was introduced, the Knights had to leave Sobernheim. The chapel was used as a commercial building and fell into disrepair. After the reintroduction of the Catholic faith in 1664, the chapel, now renovated from the ground up, served as the Catholic parish church. At the Maltese Commandry in 1821, a Progymnasium was established (the "Höhere Stadtschule" or "Higher Town School"); the chapel was restored in 1837 and was then used as the school chapel. This school is considered the forerunner to the current Gymnasium. After the new Catholic parish church, Saint Matthew's ("St. Matthäus") was built in 1898/1899, directly opposite the chapel, six tombs, the baptismal font made about 1625 and a Sacramental shrine from the 15th century were all transferred to the new parish church. The chapel building was converted into a clubhouse. The last renovation work was undertaken in 1999–2003, and since then the Catholic parish of "St. Matthäus" has been using the building as its "Haus der Begegnung" ("Meeting House"). The building is under monumental protection.
