The castle only served its royal purpose for a short time - until 1797. After the fall of the Electorate in 1806, however, it was used as a barracks, hospital, customs warehouse and customs authority. From 1842 onwards, the city library, picture gallery, antiquities museum and the Roman-Germanic Central Museum moved in. None of them remained. TV viewers are particularly familiar with the Great Hall of the city's most important secular building: the carnival session "Mainz remains Mainz, how it sings and laughs" takes place here every year.

The keep has been preserved and can be climbed. The upper (narrow) section is a bit dark, but the climb is worth it!

Electoral Palace Renaissance and Baroque building Begun in 1628, completed in 1752 The former residential palace represents the focal point of a once extensive group of buildings for the court of the archbishops and electors of Mainz. In 1478-1480, after the citizens had been subjugated in the so-called Stiftsfehde of 1462, Archbishop Diether von Isenburg had the late Gothic Martinsburg built at the north-eastern end of the city wall. It was surrounded by a moat. Together with the court chancellery built in 1555-1581 under Daniel Brendel von Homburg (1555-1582) and the St. Gangolph palace church, as well as the buildings of the Deutschhaus and New Armory from the 18th century, the palace formed a representative Rhine front. In 1628, Elector Georg Friedrich von Greiffenclau (1626-1629) began building the new palace on the Rhine side to the south of the castle. After an interruption during the Thirty Years' War, Elector Damian Hartard von der Leven (1675-1678) completed the building, doubled its length and had the baroque marble portals added on the courtyard side. With its sandstone façade richly structured by columns and balconies and the magnificent corner bay windows, the Rhine wing is one of the most important examples of the late Renaissance in Germany. In 1687, Elector Anselm Franz von Ingelheim (1679-1695) had the foundations of the north wing of the palace laid. Due to military conflicts, this wing was not built until 1751/1752 under Johann Friedrich Carl von Ostein (1743 - 1763) according to the plans of the Mainz chief building director Anselm Franz von Ritter zu Groenesteyn. He adopted the traditional formal language of the older wing in order to preserve the unity of the architecture despite the long construction history - but also to demonstrate the continuity of the electoral rule. The windows of the north facade, which faces away, show contemporary decorative forms in the Rococo style. The unusual L-shaped floor plan of the complex is explained by the corner position of the Martinsburg, from which both palace wings radiate. After the elector's flight during the French Revolution, the residential palace was repurposed as a hospital and barracks. Martinsburg, the chancellery and Gangolphskirche were demolished. The remains of the warehouse building in the castle courtyard, which were rebuilt after the Second World War, still bear witness to its use as a customs warehouse under Emperor Napoleon I. Since 1842, the city has used the castle for cultural purposes and set up museums there, including the Museum of Antiquities, the Gutenberg Museum and the Roman-Germanic Central Museum, which remained in the Rhine wing until 2021. As part of the extensive restoration from 1903 to 1925, the facades were enriched with portrait busts of important historical figures in the window gables. In 1942, the castle and its magnificent historical interiors burned down after an air raid. It was rebuilt as an event and museum building from 1948 to 1950. As part of the current renovation, the facades were given back their historical red color in sections from 1990 onwards; the windows were reconstructed in the original oak wood. The Mainz Monument Network, the German Foundation for Monument Protection and the State of Rhineland-Palatinate support the measures taken by the state capital Mainz.

A special place of experience and at the same time a natural local recreation destination is located between the city center and the Main: the Rüsselsheim Fortress. With its more than 600-year history, the fortress is not just a place where you feel transported back to the time of Landsknechts and princes. On a tour of the wall and through the ditch, you can discover the defense system and learn more about the life of the lansquenets behind their meter-thick walls. The early modern Hessian state fortress, with its origins in 1399, is also home to the award-winning City and Industry Museum, which offers tours of the fortress. Ramparts, roundels, outer and inner ditch are explored. The small exhibition in the well room, which is otherwise not accessible, contains impressive excavation finds from the extensive defense work.

The Electoral Palace in Mainz is the former city residence of the Archbishops of Mainz, who as such were also Electors and sovereigns of the Electoral State of Mainz. Wikipedia

Here you can find information about Landskron Castle: https://de.m.wikipedia.org/wiki/Burg_Landskron_(Oppenheim)

story Before Landskron Castle was built, there was probably a Salic or Hohenstaufen fortification on the same site, which was owned by King Henry V and destroyed in 1118 by troops of Archbishop Adalbert of Mainz. The castle itself was probably built in the early 13th century. The oldest surviving written mention of the "Reichsburg Oppenheim" comes from 1244. This castle was destroyed in 1257 and 1275 by the citizens of Oppenheim in a dispute with the Burgmannen over their privileges. However, Rudolf von Habsburg forced the citizens to rebuild the castle by 1281. In 1375 Emperor Charles IV pledged the castle to Ruprecht von der Pfalz. Accordingly, Ruprecht had the castle expanded. He was succeeded by his grandson Ruprecht III. as the owner of the castle, who also died there. In 1615, Elector Frederick V had the castle rebuilt like a palace. The castle burned down in the Thirty Years' War during the town fire in Oppenheim
