Thanks to a note suggested adding a Via Crucis station, I checked how similar routes in Switzerland are mapped in OpenStreetMap.

OSM tags relations for these with worship=stations_of_the_cross (and type=route route=worship ).

These relations model outdoor paths, not stations located inside a single church building.

• They can be found in traditionally Catholic regions of Switzerland. The ones mapped in OSM are mainly in Ticino and the canton of Solothurn (Soleure).
• Traditionally there are 14 stations, sometimes 15 stations.
• The monuments at stations vary: stones, crosses, sculptures, shrines or chapels.
• Distances and ascent vary: The ones at Sant’Abbondio and Astano follow the walls of the churchyard, the one to Madonna del Sasso has an ascent of almost 200 m.
• Some paths are old (18th or 19th century), others are more recent.
• The state of preservation varies greatly.
• Many routes lead to a chapel.
• Some paths to chapels feature stations on other subjects. These have route=worship , but not worship=stations_of_the_cross .

RSI counts 54 in Italian-speaking Switzerland; the scope may not match OSM’s outdoor-route tagging. OSM has 10 Via Crucis in Ticino.

OSM has about 2000 wayside crosses and 1200 wayside “shrines” in Switzerland. Some could be part of Via Crucis that aren’t mapped yet.

Here is a short clip of the one above Biasca and a longer video about the one at Klingnau.

Mapping

Depending on the location and the structure at each station, they can sometimes be mapped with aerial imagery. Generally paths are already mapped, sometimes also stations (as wayside crosses or shrines) and chapels at the end of the paths (at least as building).

Basic mapping for a Via Crucis route:

• 1 relation for route
• 1 start node
• 1 or many ways for the route
• 14/15 nodes for station
• 1 way for chapel at the end

osm.wiki/Tag:worship=stations_of_the_cross#Fixme has a checklist to improve them.
