Belgium has such a place of its own: https://en.wikipedia.org/wiki/Baarle-Hertog

However India-Bangladesh has enclaves of a higher nesting order.

Allegedly it's because local rulers were playing carrom, and were betting villages.

Once Britishers came, Bengal was separated from the rest of India along their borders of their territories.

This is another interesting one. A part of Russia that sits on the Baltic Sea disconnected from Russia proper: https://en.wikipedia.org/wiki/Kaliningrad_Oblast

That was basically East Prussia and they forcibly removed the Germans.

And the city of Kaliningrad might be more familiar in this crowd under its old (Prussian) name of Königsberg (as in "Bridges of").

One day that will cause a major geopolitical headache. And now every time I move around in that area it causes me a huge detour. Oh, and I ended up accidentally at the Belarussian border one day (note to self: update your satnav).

Little video on that https://m.youtube.com/watch?v=r-aIzkvPwFo

I don’t even have to click the link to know that it’s that episode of Map Men.

Wow this is crazy. But at the same time, it could be an interesting solution for other disputed borders around the world. Leaders are often obsessed with drawing a clean line between 2 areas but reality is a lot more messy and nuanced.
