Hidden in Mainz’s Zahlbachtal valley stands St Achatius a testament to a bygone era. This unassuming church is unique. It’s the sole surviving Mainzer church built during Napoleonic times.
Imagine the year 1809. French architect Francois-Auguste Cheussey oversaw its construction. He designed a classicist structure. A simple hall with an apse and a tall bell tower. This design reflects the architectural style of the period. The church’s length measures approximately 30 meters its width 13 meters.
St Achatius’s history stretches far beyond Napoleon. Records show a chapel existed in Zahlbach as early as 1190. This original structure was linked to the Victorstift. Later Archbishop Konrad of Wittelsbach transferred it to St Stephan’s Cathedral in Mainz. The cathedral maintained patronage rights until 1802. Even today you can find gravestones in St Stephan’s cloister. They mention “plebanus de Zahlbach” highlighting the close historical ties.
The old chapel underwent renovations around 1580. Despite the Reformation’s sweep across Europe Zahlbach remained largely Catholic. A Würzburg state archive document from 1548 describes the parish priest as “Catholic and honorable.”
The Thirty Years’ War disrupted religious oversight. In 1641 Zahlbach’s spiritual care passed to Bretzenheim. Zahlbach residents protested for centuries. They appealed to archbishops for their own priest. Their efforts continued until 1927 when St Achatius finally became an independent parish.
Construction of the current St Achatius faced many setbacks. A testament was written in 1791. It stipulated the church’s construction. The benefactor left 6860 gulden. The funds were to ensure the church’s construction and weekly masses. War and political upheaval further delayed construction. The Napoleonic Wars and subsequent shifts in power caused major disruptions.
Finally in 1808 the French prefect granted permission. Cheussey created a new cost estimate of 18126.43 francs. Building began in 1809. The main construction concluded by 1810. However financial problems halted further work.
The church’s consecration took place on November 26 1816. Bretzenheim’s priest Franziskus Chambion officiated the ceremony. Even then the church was far from finished.
The interior is austere. The high altar stands out. It dates back to around 1780. It likely originated from the abandoned Maria-Dalheim convent. Other furnishings are mainly from around 1820. Notice the Immaculata a Rococo figure. There is also a 17th-century painting of the adoration of the Christ child. The organ is a unique piece. Its pipework is from Aspisheim’s Protestant church. The case probably comes from Dalheim convent.
St Achatius in Mainz is more than a church. It embodies resilience faith and the enduring spirit of a community. Its story spans centuries reflecting the changing landscape of this vibrant city.
