<https://it.wikipedia.org/wiki/Chiesa_di_San_Michele_Arcangelo_%28Busto_Arsizio%29>
I see absolutely no problem for this church to be in Wikidata; in fact, it
is already :
https://www.wikidata.org/wiki/Q3671260 with multiple
properties (and many more esay to add).
The P1435 could be a bit tricky but nothing impossible.
I don't see any problem.
