Perched dramatically on a forested crag above an Alpine meadow, Schloss Altpernstein dominates this striking real-photo postcard — the Kleiner Priel's snowy limestone peaks gleam on the horizon behind the medieval castle, a scene of austere Upper Austrian grandeur that has barely changed in centuries. Uniquely franked with a large violet cachet reading "Schloss Altpernstein / OÖ-Österr." in lieu of a postal stamp, this card was addressed to Friedrich Rauch, Amtsassistent, in Rohrbach, Upper Austria — a glimpse of official correspondence from a castle with an active estate administration. Altpernstein, dating to the 12th century near Micheldorf im Kremstal, was a storied aristocratic seat and today serves as a youth hostel.
