Hi Cee Gee why don’t you try to be a bit more cooperative.  When using the Category Mediterranean Region, Turkey, I see no conflict to the principles stated in Wikipedia:Overcategorization. Province and geographical region are two different things. In most cases, the region doesn’t cover the whole province. For example, half of Muğla Province is in Aegean Region and the the other half is in Mediterranean Region. Similarly different parts of Kahramanmaraş Province are in four different regions. Thus both the region and the province can be used for a geographical features. Cheers.
