I don't think churches / temples are really monuments, at least that's 
not their primary purpose. That purpose is to provide a place of 
worship. I think a tower can be a monument (and tagged as such), if that 
is why it was built.

I think both monument and memorial are (usually) for structures in 
memory of something.
The difference is more about the relative importance - ie if its the 
most important one in the country, and famous etc, then its a monument. 
If its just for a fairly local event or single person, then its a memorial.
So not so much about the physical size, though monuments are usually 
bigger than memorials.

Though its true that this is poorly defined, its not always clear 
whether to tag something as a monument or memorial.

I think its best to have one generic tag, for any structure in memory of 
something/someone, eg historic=memorial.
Then use extra tags to specify what it is in memory of 
(memorial:topic=), plus the physical style (statue, obelisk). Maybe also 
a tag for the relative importance/significance, eg is it just a village 
memorial, or is it of national importance.
