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 are likely thinking of the British cannonball embedded in the wall of Saint Paul's Episcopal Church in Norfolk, Virginia. It was fired by British ships during the shelling of the city on January 1, 1776—months before the United States declared independence."
