History+
The origins of Castello di Andraz date back to around 1027, when it was erected to oversee the “Iron Road.” This route was crucial for transporting iron from the Monte Pore mines. A family from Buchenstein is noted as its first owner. In 1091, Emperor Henry IV granted the lordship of Buchenstein to the Prince-Bishopric of Brixen. In the 12th century, the Brixen vassals from Rodenegg and Schöneck received large portions of the property as fiefs, with the Schönecks eventually becoming the sole lords. Around 1200, the Lords of Buchenstein sold the castle to the Bishops of Brixen.
