Kamenický Šenov - pilgrimage stop

Pilgrimage stop at the Kamenickošenovský settlement of Pískovec I. there is a picture of a guardian angel watching over a sleeping child painted on a rock. It is decorated with a forged lattice. Below it is a wrought-iron candlestick, and even lower down is a small niche carved into the rock. Unfortunately, I could not get more detailed information.
