The Mainz Citadel is one of the most significant architectural monuments in the city and is one of the few modern citadels still preserved in Germany. Within a compact area, 2000 years of Mainz city history can be discovered – from the Roman Theater to the Lutheran Church of the 20th century.
Built in 1660 on the Jakobsberg, the citadel was a central part of the Mainz fortress. Its strategically advantageous position in the Holy Roman Empire gave it historical significance, and it was later integrated into the Grand Duchy of Hesse and expanded into a federal fortress. Despite multiple occupations and being used as a shelter during bombings, it is today one of the few modern citadels still preserved in the Federal Republic.
Today, the citadel houses municipal offices and serves as a vibrant cultural venue. In addition to the traditional Citadel Festival, the Christmas Market, numerous concerts, and festivals take place here. The fortress also provides space for modern event formats such as the “Open Ohr Festival,” attracting visitors of all ages.
Exciting tours – some in historical costumes – provide insights into the above and underground pathways of the citadel. More information and online tickets can be found at www.zitadelle-mainz.de/fuehrungen:
The centuries have left their marks: masonry, ramparts, and ditches are partly threatened by vegetation. Since 2004, the initiative Zitadelle Mainz e.V. (IZM) has been committed to the preservation of the complex. The non-profit, independent association advocates for an ecologically sustainable restoration of the walls, the careful development of the citadel ditch considering monument and nature conservation, as well as the further cultural use of the fortress.
