It was a beautiful sunny day in Mauthausen, a sign read "family friendly city" when I re-entered it after having visited the outskirts of town. Most houses were deserted but the traces of people were still there. Somebody had just been reading a book on the bench outside her house while drinking coffee. Flowers had been watered. The gardens were all in perfect order. Swimming pools looked shiny and tempting. When I walked through the city center I saw where they all were. Either on the terrasses drinking a cool drink or in the leisure center, swimming and sunbathing.Earlier on, up on the hill from where you can see the mountains, I had seen swallows, lots of them, flying low over the concrete floors, circling around the stone buildings, almost touching the barbed wire.
