It was the residence of the knights of Vipava until the mid-14th century, when it became a ducal fief, granted to a long series of noble and knightly families, including the knights of Rihemberk, lords of Snežnik and Belopeš, Counts of Celje, barons Herberstein, Counts Thurn, the noble family of Edling, counts Thrillegkh, and finally the counts Lanthieri, who abandoned the decaying castle in the 17th century.
Historically, the upper eastern part of the valley, including the town of Vipava and half of the town of Ajdovščina, used to belong to the Duchy of Carniola (specifically, to Inner Carniola), while the lower western part was incorporated in the County of Gorizia and Gradisca and thus to the Austrian Littoral.
