20 years ago, we visited the town where my dad’s great-grandfather was born, in Lorraine, France. Actually, there were two towns, back to back. We couldn’t tell where one left off, and the other began. The then-mayor of Town A was originally from Town B, and vice versa. However, the two towns had been feuding since at least the 1820s.
Among other things, we were told that, when they built the current church, c. 1820, it was supposed to be built in the middle. However, one of the towns claimed to have paid more money toward the building, and so had it located on their side.
My dad asked whether they were arguing about anything at present. Yes, something about the height of the cemetery wall.
