Tagging historic place

I looking for guidance on how to tag a building that has changed use recently. Currently, the database shows two objects for the same property. Originally, there was a seminiary in the building which has subsequently been redeveloped into a senior condo use.

My questions are should the two nodes be merged into one?

And how can you document (or Tag I guess) a former use of the building?


There’s nothing solid but there are some interesting proposed tags. Feel free to use!
