Turjak is best known as the location of Turjak Castle, a large 13th-century castle, greatly rebuilt in the early 16th century, one of the best-known and best-preserved castles in all of Carniola.[4]
The ruins of a smaller and older castle known as stari grad Turjak 'Old Turjak Castle' stand on a rocky promontory above the Želimlje Valley. It was probably built by the end of the 11th century and was the original residence of the Auersperg family, predating the better-known castle just to the southeast.[5][6]
