Church

Tenement house containing a church, it is still building=apartments not building=church
building:use=place_of_worship is an acceptable addition
amenity=place_of_worship would be also mapped

Church building no longer used for religious purposes, converted into apartments. building:use=apartments building=church would be a correct tagging here

• Tag:building=church: for a building constructed as a church, but note this does not indicate the current use.
• Tag:amenity=place of worship + religion=christian: somewhere used as a Christian place of worship. Often it is also a building=church, but not always.

Three cases

1. Built as a church, used as a church: building=church + [ amenity=place_of_worship + religion=christian ].
2. Built as a church, used for something else or closed: building=church + tags for current use.
3. Built as something else, used for Christian worship: building=* + [ amenity=place_of_worship + religion=christian. E.g., warehouse building converted into place of worship.
