Relatively far outside the villages within the nature park, isolated on the side of the road, the biker encounters a stone-carved statue (or rather, a relief image) of the Virgin Mary, holding her son Jesus on her lap. The divine child, in turn, holds a globe crowned by an oversized cross – a double symbol: The globe signifies Jesus as Lord of the world, while the cross refers to his death, which the Son of God endured out of love for us humans in order to redeem us.

The coolness in these gorges is much appreciated when it's close to a heatwave on the plains! And the wild atmosphere of the small road through these gorges (before reaching a busy road for a beautiful descent) is good (a little "kick in the ass" to get out!).
