August 10, 2025, Todesstiege and Quarry at Mauthausen Concentration Camp Memorial

Today, I saw the new fence for the first time, along with the automatic gate that closes when the number of people on the stairs exceeds 300. It's encouraging that there's now an official way to climb these stairs to the memorial again. This massive and certainly very expensive security system with its many video cameras does seem a bit absurd!

The "Stairs of Death" at the Mauthausen Concentration Camp Memorial, closed since 2018, is once again freely accessible. According to ORF, the staircase connecting the former Mauthausen concentration camp with the adjacent "Wiener Graben" quarry has been open to visitors – at their own risk – since April 1, 2025. https://ooe.orf.at/stories/3299601/ https://www.mauthausen-memorial.org/de

Wonderful circular hike away from the hustle and bustle in the hilly Mühlviertel landscape. The legend of the devil (information board at the summit cross) is really brilliant, a clever farmer😜

Such rock formations are more commonly found further north in the Mühlviertel region. A great destination for a day trip that is easy to reach or can be explored via a beautiful circular hiking trail: https://www.komoot.com/de-de/tour/2058392409

I don't know - a cyclist in front of the Stairs of Death (photo by Martin T.) - ridden or pushed - it doesn't matter - a bicycle has no place in a place like this!!! Here, where so many people have lost their lives... - I would never push a bicycle across a cemetery either. The quarry is a place of remembrance and devotion that deserves to be treated with respect.

The hiking trail is also wonderful when coming up from Windegg. The last stretch to the rock formation is then a matter of personal judgement.
