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!

Only one freestanding tower remains of the former Schwabsburg Castle. This tower, made of massive, bossed ashlars, was once the keep of the complex. Located on a Roman military road leading to Mommenheim, it once served to protect and maintain the power of the Hohenstaufen dynasty in and around Nierstein and Oppenheim. Where the castle was built is unknown, but a connection to the construction of Landskron Castle in Oppenheim is suspected, which suggests a date between 1125 and 1245. These buildings were destroyed by the Spanish in 1620 during the Thirty Years' War. Although no further remains of the complex exist, old sources mention a dining hall, a curtain wall, and various residential and commercial buildings. https://www.rheinhessen.de/a-burg-schwabsburg

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

Schwabsburg Castle is the ruins of a hilltop castle at about 120 m above sea level. NN, on a mountain spur, U-shaped surrounded by the Schwabsburg district of the town of Nierstein in the Mainz-Bingen district in Rhineland-Palatinate. Fast Facts The Schwabsburg was probably founded around 1210 and found its first documentary mention in 1257 in a royal document from Richard of Cornwall as a base of the Hohenstaufen rulers on the Rhine. In the 14th century the castle was pledged to the Archbishop of Mainz for 60 years and then became the property of the Palatinate Electors. Knight Wigand von Dienheim († November 26, 1331) was given Schwabsberg Castle as a fief in 1316 because of his high reputation with Emperor Ludwig IV (HRR). In the Thirty Years' War, the castle, like the entire Lower Palatinate on the left bank of the Rhine, was destroyed from 1620 by an army led by the Spanish general and general Ambrosio Spinola or his successor Gonzalo Fernández de Córdoba from spring 1621. In 1799 the castle was demolished after it was auctioned off.
