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:
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
