Mainz Citadel

The Drususstein (Drusus stone) is a nearly 20 metres high masonry block of Roman origin on the grounds of the citadel of Mainz, Germany. It was originally cased in marble. Researchers now largely accept that this is the structural remnant of the cenotaph mentioned by writers such as Eutropius and Suetonius, erected in 9 BC by Roman troops in honour of the deceased general Drusus, in Mogontiacum (now Mainz). During the early days of the Principate the Drususstein was the starting point for elaborate memorial services in honour of Drusus, and the centre of the imperial cult in Mogontiacum. A procession road linked it to the theatre of Mogontiacum, which contained approximately 12,000 seats, making it the largest known theatre north of the Alps. It may have hosted a part of the annual ceremonies at the day of Drusus' death, and probably also at his birthday.After being robbed of its marble casing in the early Middle Ages, the Drususstein served as a watchtower in the fortifications of the city in the 16th century. For that purpose a staircase and doorframe were made in the structure, which had been up to that point a solid building. Besides the pillars of aqueducts and the stage of the theatre, the Drususstein is one of the few remaining visible reminders of Roman Mogontiacum. Together with the Igel Column, it is the only funerary monument north of the Alps dating from antiquity that remains in its original location.

The Roman Theatre in Mainz, Rhineland Palatinate (ancient Mogontiacum) was excavated in the late 1990s. It is located immediately next to the Mainz Römisches Theater station and was once the largest Roman theatre north of the Alps, with a diameter of 116 metres, a stage-width of 42 metres, and a capacity of roughly ten thousand people.

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.

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.

BioNTech SE ( bee-ON-tek; or bye-ON-tek short for Biopharmaceutical New Technologies) is a German biotechnology company based in Mainz that develops and manufactures active immunotherapies for patient-specific approaches to the treatment of diseases. It develops pharmaceutical candidates based on messenger ribonucleic acid (mRNA) for use as individualized cancer immunotherapies, as vaccines against infectious diseases and as protein replacement therapies for rare diseases, and also engineered cell therapy, novel antibodies and small molecule immunomodulators as treatment options for cancer. The company has developed an mRNA-based human therapeutic for intravenous administration to bring individualized mRNA-based cancer immunotherapy to clinical trials and to establish its own manufacturing process.In 2020, BioNTech, partnering with Pfizer for testing and logistics, developed the RNA vaccine BNT162b2 for preventing COVID-19 infections, which at the time offered a 91% efficacy in preventing confirmed COVID-19 occurring at least 7 days after the second dose of vaccine. On 2 December 2020, temporary HMR authorization was granted by the United Kingdom government for BNT162b2 vaccinations within the United Kingdom. It was the first mRNA vaccine ever authorized. Some days later the vaccine also received an emergency approval in the United States, Canada and Switzerland. On 21 December 2020, the European Commission approved BioNTech/Pfizer's coronavirus vaccine in accordance with the positive recommendation of the European Medicines Agency (EMA).
