Zitadelle

Has anyone ever told you how a Roman monument, a medieval abbey, and a 17th-century citadel could all occupy the same hill? Here at the Zitadelle Mainz, they do. The Zitadelle in Mainz isn’t just a fortress. It’s a layered chronicle of history, etched onto the Jakobsberg hill. The oldest visible layer dates back to 9 BC with the Drususstein, a Roman monument. Imagine the Roman settlement of Mogontiacum spreading out below, the amphitheater possibly still visible from this vantage point. Centuries later, the hill became home to St. Jakob’s Benedictine Abbey, founded in 1050. However, its location just outside the city walls made it a tempting target. Repeated attacks demonstrated the strategic vulnerability of this position. The hill’s defensive potential wasn’t fully realized until the 17th century. Around 1620, the Schweickhardtsburg, an irregularly-shaped fortress, was built to strengthen Mainz’s defenses, finally integrating the Jakobsberg into the city wall system. This was the precursor to the Zitadelle as we know it today. The transformation took place around 1660 under Johann Philipp von Schönborn. The older fortress was reshaped into the imposing, quadrangular citadel we see now. Remarkably, both the abbey and the Drususstein were preserved within its walls. Over the years, the Zitadelle evolved. A commander’s building was constructed over the city-facing gate in 1696, incorporating the existing gateway. The abbey was mostly destroyed during the siege of 1793, but some elements were incorporated into later military buildings. The Zitadelle in Mainz served as barracks for Prussian and Austrian troops, then as a prisoner-of-war camp during both World Wars. The most recent historical layer of the Zitadelle are the air raid shelters in the Bastion Drusus, a stark reminder of the city’s experience during WWII. Today, the Zitadelle is a fascinating blend of its complex past and its present role as a hub for city offices and cultural events. It’s a reminder that history isn’t just something we read about, it’s something we walk on, stand beside, and look up to, especially here at the Zitadelle in Mainz.
