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:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
