The impressive choir of the church built around 1330 for the Antonites still stands today. Along with the Carmelite and Reichklaren churches, it is one of the three preserved monastery churches from the Gothic period. From 1620 until the secularization in 1802, it served the Poor Clares. The single-aisled choir contains a complete cycle of paintings from the time of its construction, the only one of its kind in Mainz. The paintings were uncovered and supplemented in 1948, so that the uniform overall image conveys the original spatial impression well. Fine linear designs are painted 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).
