The castle was mentioned in 1367 as Bray in a document by Aquileia patriarch in which was given away for one year to his vassal Dujam of St. Vitus from Rijeka. After the Uskok War (1615–17) in which was devastated castel St. Martin at Posert, the previous center of the estate, Daniel Barbo von Waxenstein built this castle in the vicinity as a new residence. It was in the possession of his descendants until 1668 when along Paz, Čepić, and Kožljak was sold to Johann Weikhard of the Auersperg noble family. All this castles and estates Johann united in a single manor Wachsenstein (Kožljak), and the center from the medieval castle Kožljak by which was named, was transferred to Belaj.
