The Rajhenburg Castle dates back in the 9th century but the current construction derives from the 16th century. The original structure was demolished at the beginning of the 10th century, but Bishop Konrad of Salzburg had it renovated between 1131 and 1147. The most prominent owners of the castle were the Rajhenburgs, the noble Moscons, the Knights Gradeneck, the Barons Gall Galenstein and the Counts Attems.
Around 1600 the castle was transformed into a Renaissance residence. Among the recent discoveries, the frescoes from the twenties of the 16th century are worthy of special attention, as they are undoubtedly the oldest surviving castle paintings in Slovenia, with allegorical depictions of Christian virtues. On the first floor is an almost hidden secular Renaissance fresco by the Master from Marija Gradec (1530).
After 1884 Trappist monks moved into the castle, where they produced chocolate and liqueur. Then in April 1941 the Germans transformed the castle into the central camp for deporting Slovenes; during the course of World War II around 45,000 Slovenes were sent into exile from here. After World War II the castle continued to function as a women's prison.
In 1968 Rajhenburg Castle became the home of the Museum of Political Prisoners, Internees and Deportees, a branch of the National Museum of Contemporary History. This permanent exhibition closed down in 2011 and a new exhibition on the Trappist order opened in a completely renovated castle in 2013.
The Romanesque perimeter, built in the 12th century, is noteworthy for the structure and construction of the walls. The castle chapel retains its original Romanesque portal, although the two-storey building itself was sturdily reconstructed in the 16th century.
Within the castle are several profiled timber work ceilings and terraced walls. A unique feature is the architectural decoration of the inner façades.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.
