Mainz-Kastel is a district of the city Wiesbaden, which is the capital of the German state Hesse in western Germany. Kastel is the historical bridgehead of Mainz, the capital of the German state Rhineland-Palatinate and is located on the right side of the Rhine river. Kastel faces the historical center of Mainz and the two cities are connected by a road bridge. Kastel is located about one kilometer below the mouth of the river Main, where it flows into the Rhine. In its long history Kastel repeatedly belonged to Mainz and was formally incorporated into that city on 1 April 1908. Since Mainz was part of the French occupation zone (formed after World War II) and Kastel was part of the American occupation zone, the Americans ordered that Kastel be brought within the administration of Wiesbaden. On 25 July 1945, Kastel was incorporated into Wiesbaden, the Hessian state capital, and has been part of it ever since. The newly formed German federal states adapted the boundaries of the occupation zones. Therefore, Kastel is a district of Wiesbaden and part of the German state Hesse. Kastel is one of six districts of Mainz on the right-hand side of the Rhine which were separated from Mainz in this way. The separation from Mainz is the issue of intense debates by local patriots in three districts (Kastel, Amöneburg and Kostheim). Many Kastel residents feel like they belong to Mainz which reflects, apart from the administrative affiliation, the reality of everyday life. The city center of Wiesbaden is about ten kilometers from Kastel whereas the city center of Mainz is just on the opposite side of the Rhine. The three mentioned districts of Wiesbaden still bear the designation "Mainz- ..." because until today no closed formal legal act has been made up. The signs, when entering the districts, are a curiosity because they say "Federal State Capital Wiesbaden District Mainz-Kastel". On the other hand, many inhabitants of Kastel feel like they belong to the German state Hesse (Mainz was a part of the Grand Duchy of Hesse from 1815-World War II) and do not identify with Rhineland-Palatinate whatsoever. Adolphus Busch, founder of Anheuser-Busch, was born in Kastel (now Mainz-Kastel) in 1839. CB&I Lummus operated an office in Mainz-Kastel which has been bought by Alstom as of 30 October 2009.The letter processing center for Deutsche Post in the greater Wiesbaden area is located in Mainz-Kastel.

The Theodor Heuss Bridge is an arch bridge over the Rhine River connecting the Mainz-Kastel district of Wiesbaden, capital of state Hesse and the Rhineland-Palatinate state capital Mainz. The main span of the bridge is 102.94 meters (337.7 ft) long. It connects the Bundesstraßes 40 and 455. Initially it was just called “Straßenbrücke” (street bridge), later it was named after German statesman Theodor Heuss. The Romans had built a bridge in this region in 27 AD, while the first arch bridge was inaugurated on 30 May 1885. Its construction costs of 3.6 million gold marks were recouped through tolls within three years although tolls continued to be levied until 1912. The bridge was widened from 1931 to 1934 but was destroyed on 17 March 1945 by German military engineers at the end of the second World War. To forestall a second Remagen, the Germans by 19 March had blown all Rhine bridges from Ludwigshafen northward. It was rebuilt in the years 1948 to 1950 and partially reconstructed between 1992 and 1995 for a cost of 139.5 million marks.

The Main (German pronunciation: [ˈmaɪn] ) is the longest tributary of the Rhine. It rises as the White Main in the Fichtel Mountains of northeastern Bavaria and flows west through central Germany for 525 kilometres (326 mi) to meet the Rhine below Rüsselsheim, Hesse. The cities of Mainz and Wiesbaden are close to the confluence. The largest cities on the Main are Frankfurt am Main, Offenbach am Main and Würzburg. It is the longest river lying entirely in Germany (if the Weser-Werra are considered separate).

Mainz-Kostheim is a district administered by the city of Wiesbaden, Germany. Its population is 14,381 (As of 2020). Mainz-Kostheim was formerly a district of the city of Mainz, until the public administration by the city of Wiesbaden was decided on 10 August 1945. The reason for this had been the easy control of the Allied Occupation Zones in Germany, where the Rhine formed the border between the American sector and the French sector. Mainz-Kostheim faces the city of Mainz on the opposite shore of the Rhine river. In 1184 Frederick I, Holy Roman Emperor held one of the biggest diets of the Middle Ages at the Maaraue in Kostheim, the Diet of Pentecost. Occasion had been the promotion to Knighthood of is both sons Henry hand Frederic, Duke of Swabia. During the Siege of Mainz by Prussian and Austrian troops in the Napoleonic Wars Kostheim had been severely damaged several times. In the cause of the bombing of Mainz in World War II Mainz-Kostheim was subject to air raids. The Linde Group has been located in Kostheim before recent mergers, acquisitions and transition.
