Aichelberg is mentioned for the first time in 1224. Its owner was a "Reinher de Eychelberc". In 1267 and 1275 another Reinher von Aichelberg appeared as ministerial of the Carinthian dukes. After the Aichelberg family died out, the castle was moved in by the sovereign, and in 1427 it was given to the villager Hans Khevenhüller as a pawn. Four years later he was vested with rule. Since then, the Khevenhüller have been nicknamed "von Aichelberg". In the war between Emperor Friedrich III and the Hungarian king Matthias Corvinus, the fortress was largely destroyed in 1484, but was soon rebuilt. Leonard Platzer was given control in 1487 already in the possession of the Khevenhüller family, August Khevenhüller had been granted the castle before 1510. When Paul Khevenhüller had to leave Carinthia in the course of the counter-reformation, Aichelberg was sold to Hans-Sigmund Graf von Wagensberg in 1629. In 1632, he was fief by Emperor Ferdinand confirmed about the castle, his daughter Anna Regina Freiin von Breuner inherited the property in 1640. After her death, Aichelberg fell to her daughter Maria Theresia Freiin von Galler, an engraving by Valvasor in 1688 shows that the castle was already a ruin at that time. Clemens Ferdinand Graf Kaiserstein bought the estate in 1699. He died in 1724 and A ichelberg came to his daughter Maria Maximiliana Freifrau Jöchlinger von Jochenstein. The reign came in 1846 to his daughter Johanna Countess von Rosenberg through her great-grandson Felix Freiherr Jöchlinger von Jochenstein. The Orsini-Rosenberg family still owns the ruins today.
