Krumperk Castle was probably built in the late 13th century by the noble family Rabensberg from Koprivnik. The predecessor of the current castle is first mentioned in 1338 as a possession of Herkules of Krumperk, of the noble house of Kreutberg. By the 15th century, it belonged to the house of Rusbach, which sold it to Engelhand Zellenperger in 1410 under the name Turn Chraw-perg. Valvasor notes that it had once been called either Thurn unter Kreutberg or Thurn zu Kreutberg, although there is confusion as to which of these names referred to Krumperk Castle and which to the ruin of Koprivnik (Rabensberg) Castle near Moravče.
At the end of the 16th century, the male Zellenperger line became extinct, and the castle passed by inheritance accord to the older branch of the house of Rauber, one of the most prominent noble families in 15th and 16th century Carniola, who were later elevated to barons. The best-known member of the family was Adam von Rauber, who participated in the Battle of Sisak. At its height, the Krumperk lordship contained the settlements of Dob, Ihan, Krtina, Brezovica, and Studenec.
The Raubers replaced the old castle with the current building in 1580. Their line eventually became extinct; the daughter of the last Baron Rauber was the mother of the historian Johann Weikhard von Valvasor. The next owners, in 1631, were the Rasp family, followed by the counts Thurn-Valsassina, then in 1840 the barons Rechbach, who in 1928 moved to Austria after selling the estate to its final private owner, Stanka Pogačnik, a landowner from Ruše near Maribor.
After World War II, the castle was nationalized and stripped of its furnishings. The communist authorities converted the structure into a sanatorium for wounded military officers; in 1953, it was given to the Municipality of Domžale, which subdivided it into apartment housing. In 1985, the Krumperk holdings were partitioned; the castle went to Agrokombinat and the estate was taken over by Biotechnical Faculty of the University of Ljubljana, which established an equestrian center.
Today, the castle is the subject of a denationalization proceeding and is in a fairly poor state of repair.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.
