Hohenwerfen Castle, from a train window. I’ve been to this pile of rocks a couple of times in the past, when I lived somewhat closer to it. The last time was by invitation of a colleague on her birthday — a tour of the castle, lunch and a falcon show. There is a falconry on the premises.
Wikipedia tells me that the castle has been used as a location for the 1968 film Where Eagles Dare as well as the 2003 Ashton Kutcher film Just Married. (Tja!) It also supplied the backdrop for a scene in The Sound of Music (it’s just a bit of a drive down from the town of Salzburg).
And, since we’re on the subject of Salzburg and films, the Salzburg Museum is featuring a photo exhibit right now called Help! The Beatles in Salzburg — Photographs by Christian Skrein. The photographs document the band’s visit for a location shoot in the Obertauern Region (Why did they fly all the way to Austria for that sledding scene? It may have been the only snowy, mountainous area where they wouldn’t be dogged by fans. In fact one of the groups which came out to meet them held up signs which said “Beatles Go Home”.)
