Podčetrtek belongs among the oldest castles in Slovenia. It was once located at an old national border, at Sotla river facing Croatia or Hungary. Podčetrtek is located in the area which already in 1071 became a property of Krško diocese. The construction of the castle can be dated to a time after the first third of the 12th century. First written record dates from 1361.
On 12th of November 1441 bishop of Krško Johan temporarily gave his castles Pilštanj, Podčetrtek, Bizeljsko and Mokronog to emperor Friderik IV who kept them until 1445, Afterwards the castle was governed by managers and between 1479 and 1490 it was in the hands of Hungarian army. In 1515 the castle succumbed to peasant revolt.
In 1527 the castle possession was moved to Hans Tattenbach and his successors leased and rented the castle and in 1612 Krško diocese imparted them the castle as heritable or private possession. At the execution of Erazem Tattenbach in 1628 the castle was confiscated by the province from which Ignac Attems. The castle was completely renovated in 1874 and remained a property of Attems' until the World War II.
After the war when the castle became a general public property it served various purposes and gradually it was soon completely robbed. Only a few artworks were rescued and are stored by Posavski muzej in Brežice. Nowadays it is abandoned.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
