Oh. Thanks Boris!Buttresses are found all over Now, but the first "Gothic" church using them was the Church of St Denis, in Paris, France in 1136 CE.
Since the buttress' (flying buttress, to be exact) is just an architectural feature of a building, I suggest a better candidate for this would be something like Buttressed Cathedral or Gothic Cathedral (even though, of course, both of those are found all over Europe as well) which supplies both Faith Points when built and also possibly Production Points because of the extra expertise among the master builders from erecting these structures - French masons and builders were hired to put up structures all over Europe in the late Medieval period, after all.
The buttresses is revenge for Notre Dame not being in Civ 6
I may do America, Rome, the Byzantines, China, or Germany next.
