Two things I noted while using this app. Map making is certainly not the art form it used to be, look at that amazing detail (look at the Notre Dame Cathedral below). And secondly, the first manned hot-air balloon didn't happen until 51 years after this map was made - yet this map is surprisingly accurate in the layout of the Paris landscape and Seine River.
