This feature has been labeled as deprecated
. The recommended replacement is: historic=wayside_shrine or sometimes amenity=place_of_worship + religion=christian.
The reason is documented in Deprecated features
. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct
. Any such change will be reverted.
The tag historic=wayside_chapel was introduced by mistake to map a small place of worship or shrine alongside a road.
The tag historic=wayside_shrine should be used instead in most cases, with religion=*
For a small Christian place of worship, use amenity=place of worship + religion=christian
In case you can enter the building, see building=chapel, if you normally can't enter the building (e.g. the scene is intended to be viewed from outside), see building=shrine.
