Oh God, this is wonderful. Now (of course) we'll start asking for "ruined", "savage", "evil", "coastline", "pious", "fortified" variations... ๐
Well, actually those icons are (fantastic and) huge: i mean, while they are very clean and with minimum detail expressed, they are big enough to be useful to describe very different kind of buildings.

However, in the meantime we can dream ๐
