The earliest known documentation of the castle was in 1121, when it was referred to as "Glenekke" and was owned by Duke Henry III of Carinthia.

[1] Upon the death of Henry in 1122, ownership transferred to his nephew, Count Bernhard von Marburg and later Otakar III.

After three more owners, in 1534, King Ferdinand I owned the castle, but he had to sell it to Ulrich von Ernau because of his debts.

In 1818, Hofrichter Hirzegger from Ossiach purchased the castle to give to his daughter Josephine as a wedding present.

The building comprises various architectural elements, ranging from Romanticism to Renaissance.
