The impressive choir is mainly preserved from the church built around 1330 for the Antoniters. The church is one of the three remaining Gothic monastery churches in Mainz, alongside the Carmelite and the Reichsklaren churches. From 1620 until the secularization in 1802, it served the Poor Clares.
The single-naved choir has a complete cycle of paintings from the time of construction – the only one of its kind in Mainz. The paintings uncovered in 1948 were completed, allowing the cohesive overall picture to convey the original spatial impression well. Filigree traceries are visible in the vault fields, between which various saints are depicted. At the apex of the choir, Christ is enthroned, flanked by Mary and John the Baptist (Deesis).
