Cekin Mansion on the northern edge of Tivoli Park houses the Museum of Contemporary History of Slovenia. The mansion is named after Laurenz Szőgyény, the husband of Ivana Lamberg, who was given the building. The name Szőgyény was Slovenized by the townspeople into Cekin.
The mansion was commissioned in 1720 by Leopold Lamberg based on plans by the Viennese Baroque architect Fischer von Erlach. During the last years of the French occupation of Ljubljana from 1812 to 1813, it was used as a temporary residence by Eugène de Beauharnais, the viceroy of Italy and the commander of the Napoleonic armies in the Illyrian Provinces. In the mid-19th century, the mansion was purchased by the Slovenian patriot Peter Kosler, who lived there until his death. After World War II, the mansion was nationalized by the Communist authorities of the People's Republic of Slovenia. From 1990 to 1992, the mansion was renovated by the engineer Jurij Kobe, who also added a communication tower. For his work, he received the Plečnik Award, the most prestigious Slovenian award in architecture.
Since 1951, the mansion has housed the Museum of Contemporary History. The museum includes collections from World War I, the interwar period, World War II, postwar Yugoslavia, and independent Slovenia. This includes many historical items, including archives, artworks, and photographs.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
