Peculiar border between Belgium and the Netherlands

The Belgium-Netherlands border, particularly around the Baarle region, is known for its incredibly complex and winding nature, featuring enclaves and counter-enclaves, with the border crisscrossing streets and even houses.

The border between Belgium and the Netherlands is notorious for its complexity, especially in the area of Baarle, where Belgian territory (Baarle-Hertog) is partially surrounded by Dutch territory (Baarle-Nassau), and vice-versa.

In Baarle, the nationality of a property is determined by which country the front door faces, leading to houses, shops, and even restaurants being divided by the border.

Many residents of Baarle-Nassau and Baarle-Hertog hold both Dutch and Belgian passports due to the complex border situation.
