A few generic changes proposed:
Suggest add "Scientific" to Education?)
Done. Made it "Science and Education".
change that name to "Rivers, wetlands and lakes".
The difference between Residence and Palace is blurry
It is. Though not all residences are the same, I could see some move to a combined Palace/Residence category (they're in fact upper class housing). But we have others in the Residence category which do not fit that easily, they are more normal houses (Rietveld, FLW, Decorated farmhouses). We could make a more disruptive move and call it all Housing?
