Unfortunately obvious historic=castle fails - as it is defined and
used as "(often fortified) buildings from medieval and modern times"
and includes nearly everything - for example "Representative building
without functional defenses.". (see

IMHO, defining too specific objects, and more and more of them, is a
mistake.<br>
The first problem with castles is to call them historic.<br>
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?<br>
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).<br>
<a href="https://fr.wikipedia.org/wiki/Ch%C3%A2teau_Latour">I picked
just one at random</a> and I see that <a
href="http://www.openstreetmap.org/node/1914563248">it is tagged
building=yes.</a><br>
If that's how to recognize a château, there is a huge number of
them!<br>
<br>
I suggest that a castle/château/whatever should be<br>
building=castle<br>
historic=yes/no/??? if castle is or not<br>
[castle:]château=yes if the castle is of that type<br>
building:hotel=yes if a "retired" castle was (totally or partly)
fitted as a hotel<br>
castle:winery=yes if the castle is used to produce wine<br>
etc...<br>
<br>
And whatever attributes we can agree upon.<br>
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.<br>
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?<br>
<br>
And to answer Pieren: no, a "château d'eau" is not a castle, it's a
tower (obviously).<br>
<br>
