The History of Jablje Castle
The castle in Jablje began its relatively brief history as a noble estate and is now well-positioned to become a sustainable hub.
The castle Jablje was first recorded in historical sources about 1520 and was built in the beginning of the 16th century. It was originally a Renaissance fortified manor house, which was later reconstructed in the 17th century into a large baroque manor house.
Noble Families That Owned Jablje
During the centuries, the castle was the property of several important noble families:
- Lamberg family
- Auersperg family
- Lichtenberg family
It was rebuilt around 1660-1680 following a devastating fire, under the direction of Johann Daniel Erberg and retains its handsome baroque facade that lies before tourists today.
World War II and Restoration
In World War 2 the castle served as a military headquarters for the Germans. Post-war it was transferred in the state ownership and worked for education at a higher professional school – Biotechnical faculty of Slovenia.
Over the years it was badly neglected, but is now being improved by a huge €7.2m European-funded project which has been underway since 2020 and has been completed in 2022. The castle today symbolises one of the most successful conservation efforts to integrate with environmental innovation in Slovenia.
