The entire roof has collapsed, 50%, the back corner still has a roof over it? Does a tarpaulin over the missing roof return it to being a building? Is Notre Dame cathedral still a "building"? & with regard to "ruins" - is there something visible on the ground? If there is, even just a pile of rubble, it should be on the map, so that someone walking past can look at the map & say "Aha, this pile of rubble used to be Whatever". Thanks Graeme
