Sooneck Castle was first mentioned around 1271. Like neighbouring Burg Reichenstein (Rhein), the castle was managed by the lords of Hohenfels as bailiffs for Kornelimünster Abbey near Aachen. What is certain is that the castle was besieged in 1282 by King Rudolph I. His troops overran and destroyed the castle and the king imposed a ban on rebuilding it, which he explicitly restated in 1290. When the castle was rebuilt it was given to an Austrian family who were fervent supporters of the Habsburgs, the Reitenaours, to stop Swiss expansion. The wars with the Swiss claimed many Reitenours: George, Robert and most famously, Nicholas, who died in the battle of Sempach. In April 1346 Archbishop Henry III of Mainz gave Sooneck Castle in fief to John, Knight Marshall of Waldeck, who subsequently had a new castle built on the site. After his death it passed jointly to four of his heirs and the castle thus became a multi-family property, or Ganerbenburg.
The branches of the family jointly residing in the castle were not on good terms and quarreled over inheritances. Several times, peace had to be legally imposed. When the line of Waldeck died out in 1553 with the death of Philipp Melchior, the Breidbach zu Bürresheim family, previously co-tenants, became sole tenants of Sooneck Castle. When that family became extinct, the castle began to fall into disrepair.
In the course of the War of the Palatine Succession, Sooneck - like all the castles on the left bank of the Rhine - was destroyed in 1689 by troops of King Louis XIV of France. In 1774, the Archdiocese of Mainz leased the ruins to four residents of Trechtingshausen who planted vineyards. The site later came into the possession of the village of Niederheimbach.
In 1834, the then crown prince of Prussia, Frederick William IV, and his brothers Princes William, Charles, and Albert bought the completely derelict castle and, between 1834 and 1861, had it rebuilt as a hunting lodge. In the rebuilding, which was designed by the military architect Carl Schnitzler, the historical structures were largely retained with the addition of buildings in romantic style. The Prussian royal crest over the north gate of the castle dates to this period. Disagreements within the royal family and the effects of the revolutions in Germany in 1848 prevented the castle from ever being used as a hunting lodge.
After World War I aristocratic properties were nationalized and Sooneck Castle became a possession of the state. After World War II it passed to the state of Rhineland-Palatinate and in 1948 to the State Ministry of Castles (today Generaldirektion Kukturelles Erbe Rheinland-Pfalz Direktion Burgen, Schlösser, Altertümer Rheinland-Pfalz). It can be visited on organized tours.
The residential areas of the castle are furnished predominantly with items in the neo-gothic and Biedermeier styles. The interiors are enriched by paintings owned by the Hohenzollern family and, since 1991, the Köth-Wanscheid family foundation, and drawings and sketches by Johann-Caspar Schneider among others.
Since 2002, Sooneck Castle has been part of the Rhine Gorge UNESCO World Heritage Site.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
