As this is a church (and a cremetorium), wouldn’t this nomination be eligible? I need convincing that it is exclusively for people praying for those who passed away and exclusively for the cremetorium. Sorry for making an out of place narrative if it’s inappropriate.
Sensitive locations such as funeral homes, burial grounds, cemeteries, and graveyards should generally be avoided out of respect, but gravestones are eligible for consideration if it is publicly accessible and it belongs to a historical figure or significant community figure.
This is a “sacred place” and should not be a game location.
There are other game locations at this church. The columbarium should not be one of them.
