The Liebfrauenplatz in Mainz is the easternmost of the four squares around Mainz Cathedral. It originally housed the Liebfrauenkirche (church of our Lady), which was demolished at the beginning of the 19th century and whose outline can still be seen today on the square, and marks the transition between the cathedral and the Rhine in the direction of the Fischtor, one of the eastward city gates.

The Marktbrunnen in Mainz is a renaissance fountain located at the ″Markt″ (market place) of Mainz. It was donated by elector Albert of Mainz and crafted in the workshop of the Mainz sculptor Hans Backoffen. The Marktbrunnen represents one of the first architectural formed decorated fountains of the renaissance.

The Iron Tower (German: Eisenturm) is a mediaeval tower dating to the early 13th century, and modified in the 15th century, which with the Wood Tower and the Alexander Tower is one of three remaining towers from the city walls of Mainz, Germany. Its name derives from the Iron Market (Eisenmarkt), which was held in the immediate vicinity until the 19th century. The Iron Tower served as a watchtower and gate to the city, and later as a gaol. It was badly damaged in World War II and reconstructed in the 1960s. Today it houses various organizations and art projects and is used for art exhibitions.

Mainz Cathedral or St. Martin's Cathedral (German: Mainzer Dom, Martinsdom or, officially, Der Hohe Dom zu Mainz) is located near the historical center and pedestrianized market square of the city of Mainz, Germany. This 1000-year-old Roman Catholic cathedral is the site of the episcopal see of the Bishop of Mainz. Mainz Cathedral is predominantly Romanesque in style, but later exterior additions over many centuries have resulted in the appearance of various architectural influences seen today. It comprises three aisles and stands under the patronage of Saint Martin of Tours. The eastern quire is dedicated to Saint Stephen. The interior of the cathedral houses tombs and funerary monuments of former powerful Electoral-prince-archbishops, or Kurfürst-Erzbischöfe, of the diocese and contains religious works of art spanning a millennium. The cathedral also has a central courtyard and statues of Saint Boniface and The Madonna on its grounds. During the time of Mainz Archbishop Willigis (975–1011), the city of Mainz flourished economically, and Willigis became one of the most influential politicians of that time, ascending to regent of the empire between 991 and 994. In 975–976 shortly after his installation he ordered the construction of a new cathedral in the pre-Romanesque Ottonian architecture style. This new and impressive building was part of his vision of Mainz as the "second Rome".This new cathedral was to take over the functions of two churches: the old cathedral and St. Alban's, which was the largest church in the area, belonging to a Benedictine abbey and serving as the burial ground for the bishops and other nobles, including Fastrada, a spouse of Charlemagne. Most of the synods and other important meetings were held at St. Alban's Abbey. The new cathedral consisted of a double chancel with two transepts. The main hall was built in the typical triple-nave "cross" pattern. As was usual at that time no vault was included because of structural difficulties relating to the size of the building. Six towers rose from the church. A cloister was enclosed in the structure and a small freestanding church, St. Mary's Church, connected by a colonnade. This small church developed later into the collegiate church of St. Maria ad Gradus. Sandstone was used as the primary building material for the cathedral. The inside was plastered white under the Archbishop Bardo, probably in the middle of the 11th century. During renovations ordered by Henry IV in the late 11th century, much of the outside was also plastered, but the cornices were left exposed in their original red and yellow. It is believed that the coloring of the cathedral was changed on a number of occasions, but no further documentation of the coloring is available until records of the Baroque works. The cathedral suffered extensive damage from a fire on the day of its inauguration in 1009. Archbishop Bardo (Bardo of Oppershofen) presided over the completion of the cathedral begun under Willigis. By 1037 the main portions of the body of Mainz Cathedral were complete. Willigis was buried in the second church he had initiated, St. Stephan's, in 1011.

Mainz, previously known in English as Mentz or Mayence, is the capital and largest city of Rhineland-Palatinate, Germany. Mainz is on the left bank of the Rhine, opposite the place where the Main joins the Rhine. Downstream of the confluence, the Rhine flows to the north-west, with Mainz on the left bank, and Wiesbaden, the capital of the neighbouring state Hesse, on the right bank. Mainz is an independent city with a population of 219,501 and forms part of the Frankfurt Rhine-Main Metropolitan Region.Mainz was founded by the Romans in the 1st century BC as a military fortress on the northernmost frontier of the empire and provincial capital of Germania Superior. Mainz became an important city in the 8th century AD as part of the Holy Roman Empire, capital of the Electorate of Mainz and seat of the Archbishop-Elector of Mainz, the Primate of Germany. Mainz is famous as the birthplace of Johannes Gutenberg, the inventor of a movable-type printing press, who in the early 1450s manufactured his first books in the city, including the Gutenberg Bible. Mainz was heavily damaged in World War II; more than 30 air raids destroyed around half of the old town in the city centre, but many buildings were rebuilt post-war. Mainz is notable as a transport hub, for wine production, and for its many rebuilt historic buildings. One of the ShUM-cities, Mainz and its Jewish cemetery is part of the UNESCO World Heritage Site.

The choir Mainzer Domchor is the choir at Mainz Cathedral, of boys' and men's voices. It was founded in 1866 by the then bishop of Mainz, Wilhelm Emmanuel von Ketteler.

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. It was located in the old town of Mainz. Today, the houses at Schusterstraße 22 and 24 are located on the site.

The church of St. Augustin known in German as Augustinerkirche, was the minster of the Augustine friars in the city centre of Mainz. Today it is the seminary church of the Catholic theological seminary of the Roman Catholic Diocese of Mainz.

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.

St. John's Church (in German Johanniskirche) is located beneath Mainz Cathedral in the historical center of Mainz, Germany. This 1100-year-old church was the first episcopal see of the Bishop of Mainz. It is the oldest church in Mainz, the oldest cathedral in the Germany of today and the only preserved cathedral building from late Carolingian and early Ottonian time in Germany.St. John's Church is predominantly Carolingian in style, but later exterior additions over many centuries have resulted in the appearance of various architectural influences seen today. It comprises three naves and stands under the patronage of John the Baptist today. It can be assumed that the church was dedicated initially to Martin of Tours since Martin is the Patron saint of the Roman Catholic Diocese of Mainz, then to St. Salvator, consecrated in 911 by Archbishop Hatto I and served as the cathedral for the Bishop of Mainz until the appointment of Willigis as Archbishop of Mainz in 975. It is documented that archbishop Erkanbald was buried in this first cathedral. In 2019, a sarcophagus was opened to gain more information on the early history of the diocese of Mainz. Whether it concerns the remains of cleric Erkanbald, buried in 1021, is investigated since then said research director Guido Faccani.

The Wood Tower (German: Holzturm) is a mediaeval tower in Mainz, Germany, with the Iron Tower and the Alexander Tower one of three remaining towers from the city walls. Its current Gothic appearance dates to the early 15th century. It is so named because wood used to be piled next to it on the bank of the Rhine.Like the Iron Tower, the Wood Tower was used as a watchtower and gate-tower and later as a gaol. It was badly damaged in World War II and accurately reconstructed in 1961 for the two-thousandth anniversary of the city. It currently houses various organisations and clubs.

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.
