IMHO, defining too specific objects, and more and more of them, is a
The first problem with castles is to call them historic.
Under the thread "château" I pointed out that there are buildings that
can be called château ≃ castle and that are not historic at all. Should
we define castle attributes for historic castles and then more or less
the same attributes for less or not at all historic ones under another
object name or instead use a single object?
I notice that since that discussion there is not yet a way to tag those
châteaux (consequently, I stopped tagging the list I had of them).
I picked just one at random
<https://fr.wikipedia.org/wiki/Ch%C3%A2teau_Latour>  and I see that it
is tagged building=yes. <http://www.openstreetmap.org/node/1914563248>
If that's how to recognize a château, there is a huge number of them!

I suggest that a castle/château/whatever should be
historic=yes/no/???  if castle is or not
[castle:]château=yes   if the castle is of that type
building:hotel=yes     if a "retired" castle was (totally or partly)
fitted as a hotel
castle:winery=yes      if the castle is used to produce wine

And whatever attributes we can agree upon.
And regarding the definition of castle itself, one may try to make a
broad definition such a a living place that's not a small one, or a
building similar to one.
But, after all, isn't the simplest, after such a broad definition, to
add "any building that meets one of the attributes that follow" and
hence to make the definition extensible by adding attributes?

And to answer Pieren: no, a "château d'eau" is not a castle, it's a
tower (obviously).
