Zwingenberg Castle (German: Burg Zwingenberg), also called Zwingenberg or Schloss Zwingenberg, stands on the right bank of the River Neckar where it cuts through the Odenwald hills in central Germany. The castle is located in the municipality of Zwingenberg in the state of Baden-Württemberg.
The spur castle was built on a hill spur in the triangle formed by the confluence of the steep Wolfschlucht gorge with the Neckar valley and lies about 50 metres above the river.
The castle was probably built in the 13th century by the Hohenstaufen ministerialis, William of Wimpfen. The first record of it dates to the year 1326. A nephew of William of Wimpfen called himself von Zwingenberg. Because the Zwingenbergs were robber knights, in 1363 they were driven from the castle and it was slighted in the name of the emperor. In 1403, the Lord of Hirschhorn was enfeoffed with the Zwingenberg and had it rebuilt. After his line had died out, ownership switched between the Electorate of Mainz, Electorate of the Palatinate and the Grand Duchy of Baden. The lord of the castle today is Louis (Ludwig), Prince of Baden (born 1937), a descendant of Grand Duke Charles Frederick of Baden.
Above Zwingenberg Castle are the remains of Fürstenstein Castle.
