In southwestern Serbia, there's a village called Medjurechje that's not Serbian at all—it's actually quite Bosnian. It's an enclave of Bosnia and Herzegovina. At least on paper, anyway.

There's no actual border there. Most people living there are Serbs, they work in nearby Serbian cities, all the shop prices are in Serbian dinars, and Serbia provides all the infrastructure. But property taxes go to Bosnia ¯\_(ツ)_/¯

There's no decent road from Belgrade on the Serbian side. It's easier to drive through Bosnia. And the border there is really strange. On the Bosnian side, the border guard didn't even look at my passport. He just waved me through, like, go ahead. Besides locals, it doesn't seem like anyone really drives through there. So the Serbs were curious asking what I was doing there and whether I was a journalist.

The enclave was formed long before Yugoslavia and has nothing to do with the Bosnian War. About 15 years ago there were negotiations about redrawing the border, but nothing came of it. And the fewer years go by, the fewer people care about it. The village population is shrinking rapidly.
