Orehek (pronounced [ɔˈɾeːxək]; German: Nußdorf,^[2] Italian: Orecca) is a village southwest of Postojna in the Inner Carniola region of Slovenia.^[3]

Nussdorf Castle

Nussdorf Castle (Slovene: Grad Orehek) is 13th-century castle on a small hill above the village. The collection of buildings showcases architectural styles dating from the 16th to the early 20th century. Still visible are remnants of defensive walls and perimeter towers. The central keep was significantly altered in the 20th century. Among its former owners are a number of prominent Carniolan noble families, including the Counts of Thurn and the princely family Porcia.^[5]
