The Old Arsenal (Altes Zeughaus), also referred to as Zum Sautanz, was the central arsenal of the fortress of Mainz during the 17th and 18th century.

The church of St. Christoph in Mainz, known in German as St. Christoph zu Mainz, is an example of early gothic architecture. St. Christoph was originally built between 1240 and 1330. The church is associated with Johannes Gutenberg, who may have been baptised there. It had been erected in Christofstraße in the historic city centre of Mainz and adjacent to the Karmeliterplatz. Its ruins represent the central war memorial in the city of Mainz, in memory of the victims and the destruction of the city in World War II, such as the bombing of Mainz on 27 February 1945.

The Christuskirche (Christ Church) is a Protestant church located in Mainz. The Christuskirche was built between 1896 and 1903 designed by Eduard Kreyßig. It was consecrated on 2 July 1903. After demolition during the air raids of World War II the church was reconstructed between 1952 and 1954. The congregation forms part of the Protestant Church in Hesse and Nassau. In the predominantly Catholic Mainz of 1802, only some hundred Protestants could be traced at the end of the Ancien Régime. Napoleon Bonaparte was the first to grant them the right of freely practising their religion and he expanded their civil rights. Previously Protestants had the status of "tolerated" human beings, a status they shared with the Jews. Around the year 1900 already 33% of the inhabitants of Mainz had the Protestant confession. Due to increase of the Protestant community, they had to search for new space. The extension of the old city borders by the new expanded town Mainz-Neustadt during the last trimester of the 19th century opened the opportunity to demonstrate the self-confidence of the Protestant community by erecting a new church building. Along with the Kaiserstraße, a new twin lined three-lane boulevard, the church was erected by Eduard Kreyßig, the master builder of Mainz, in Renaissance Revival style. The church was intended to be a representative counterbalance to the Catholic Mainz Cathedral. The mighty dome excels other churches and buildings of the inner city of Mainz. Besides services, the Christuskirche is shared by lovers of music, since Diethard Hellmann founded in 1954 the Bach Choir and Bach Orchestra to perform especially Bach's cantatas. Fans of Gospel music enjoy the yearly performances of Colours of Gospel. Traditionally the opening mass services of the University of Mainz at the beginning of the academic term take place here.

The Catholic church of St. Quintin is the parish church of the oldest proven parish in the city of Mainz. Today, St. Quintin together with the cathedral community of St. Martin forms the parish of St. Martin's Cathedral and St. Quintin. Thus the cathedral priest is therefore always the priest of St. Quintin as well.

In the siege of Mainz (German: Belagerung von Mainz), from 14 April to 23 July 1793, a coalition of Prussia, Austria, and other German states led by the Holy Roman Empire besieged and captured Mainz from revolutionary French forces. The allies, especially the Prussians, first tried negotiations, but this failed, and the bombardment of the city began on the night of 17 June.

The Battle of Mainz (29 October 1795) saw a Habsburg Austrian army led by Field Marshall François Sebastien Charles Joseph de Croix, Count of Clerfayt launch a surprise assault against four divisions belonging to the French Army of Rhin-et-Moselle directed by General of Division François Ignace Schaal. The right-most French division was completely routed and all the French troops were compelled to retreat with the loss of their siege artillery and many casualties. Clerfayt followed up his Rhine campaign of 1795 victory by driving most of General of Division Jean-Charles Pichegru's Army of Rhin-et-Moselle south. The War of the First Coalition action was fought near the city of Mainz in the modern-day state of Rhineland-Palatinate in Germany. French troops had ineffectively besieged the western side of Mainz Fortress since December 1794. However, in early September 1795 the General of Division Jean-Baptiste Jourdan's Army of Sambre-et-Meuse crossed the lower Rhine River and advanced south to the Main River. For the first time Mainz was besieged on the east side of the river, but this state of affairs did not last long. After the Battle of Höchst, Clerfayt forced Jourdan's army to retire to the west bank of the Rhine. With Jourdan temporarily out of the picture, Clerfayt fell on Schaal's somewhat isolated corps and drove it away to the south. During this time the commander of the Army of Rhin-et-Moselle, Pichegru was in treasonous contact with France's enemies, perhaps accounting for Austria's success. The next clash was the Battle of Pfeddersheim on 10 November. The siege was the second time balloon reconnaissance had been used, after the Battle of Fleurus (1794).

The Humbrechthof, also known as Hof zum Humbrecht, was the building in which Johannes Gutenberg developed his technique of printing with movable metal type and set up his first printing press.
