Is it the original town of Oradour-sur-Glane,France?
Because it was destroyed on June 10 1944 by massacre 642 people by a German Waffen-SS company...until a new town was built nearby the after the war however Charles de Gaulle (the 18th President of France) order the original maintained as a permanent memorial and museum.
And that's all I guess as for the others if my guess is wrong I hope others will get the right town.
You know, I think the Netflix Carmen would have been better if they had done good flashbacks. Carmen was a teen right? Why not do flashbacks of when Carmen and Chase were partners and working together? Or when Chase was chasing Carmen? Or more about when Carmen quit?
