The Mainz South Bridge (also known as the Mainz-South Railway Bridge, and at times as the Mainz-Gustavsburg Railway Bridge) is a railway bridge on the Mainz–Frankfurt railway line, spanning the Rhine at river kilometer 496.4 and connecting Mainz in Rhineland-Palatinate with Gustavsburg in Hesse. A footbridge attached to the north side of the bridge allows pedestrians and cyclists to cross the river.

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

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

History Before the Landskron Castle was built, a Salian or Staufen fortification probably stood in the same place, which was mentioned in 1118 as "praesidium" and was destroyed in the possession of King Henry V by troops of the Archbishop of Mainz, Adalbert. The castle itself was probably built at the beginning of the 13th century. The oldest surviving written mention of "Reichsburg Oppenheim" dates from 1244. This castle was destroyed in 1257 and 1275 by the citizens of Oppenheim in a dispute with the castle dwellers over their privileges. However, Rudolf von Habsburg forced the citizens to rebuild the castle by 1281. In 1375, Emperor Charles IV pawned the castle to Ruprecht of the Palatinate. Ruprecht accordingly had the castle expanded. He was followed by his grandson Ruprecht III as owner of the castle, who also died there. Elector Frederick V commissioned a palace-like renovation of the castle in 1615. The castle burned down in the Thirty Years' War during the Oppenheim town fire

The Rüsselsheim Fortress and the surrounding area are worth a visit. To get a good overview, it is worth walking around the fortress three times. First via the street An der Festung above the moat, then inside the moat and finally via the ramparts inside the fortress. The Wallanlage is open Tuesday to Thursday from 10 a.m. to 4 p.m. The ramparts offer a good view of the surrounding area. In the inner courtyard of the fortress there are historical buildings, a museum on the industrial history of Rüsselsheim, a cafe and the local history association.

This hiking highlight (section) also points to a tour through the fortress moat. One round is recommended. In addition to some benches, the well-preserved ramparts are visible. Only the foundations of the towers are visible, as they were blown up by the French in 1689. In winter and when it is wet, the moat can be uncomfortably cold and damp compared to the surrounding area.

The southern bridge serves the Rhein-Main-Bahn from Mainz via Darmstadt to Aschaffenburg and the Mainbahn running south of the Main from Mainz to Frankfurt (Main) Hbf, on which the S 8 line between Mainz, Frankfurt (Main) Airport and Frankfurt also runs. After the Roman bridge and Charlemagne's Rhine bridge, which burned down shortly after its completion, the southern bridge in Mainz from 1862 was the first fixed Rhine bridge in Mainz, which until then only had a ship bridge. At the same time, it was the fourth railway bridge over the Rhine after the Waldshut–Koblenz bridge on the Upper Rhine, the Kehl bridge and the Cathedral bridge in Cologne. While today it connects two federal states - Rhineland-Palatinate on the left bank of the Rhine and Hesse on the right bank - both banks belonged to the Grand Duchy of Hesse or the People's State of Hesse at the time of construction and up to 1945, to its left bank of the Rhine province of Rheinhessen and to its right bank of the Rhine province of Starkenburg .

From the imposing castle ruins, there is a great view over Oppenheim and the Rhine plain 👍 https://www.regionalgeschichte.net/rheinhessen/oppenheim/kulturdenkmaeler/burg-landskron.html
