Italy San Romedio Sanctuary

The striking San Romedio sanctuary, which honors a hermit who is said to have lived out his final years with a pet bear, is composed of five churches. They were built over a period of 1,000 years next to a steep rock wall. A 130-step staircase leads visitors up the complex that represents a millennium of Roman Catholic history.

Any camera / lens are ok.

It's best to park by the Museo Retico in Sanzeno village, where the path into the canyon starts.
There’s a road up to the canyon, but an old aqueduct (no longer in use) provides a scenic walking path up the sloping cliff.
