BBC Travel - Europe's strange border anomaly

This is a political map of the area, and here are the borders superimposed on a geographical map.

Some choice excerpts:

Because of its location, Belgium had to seek Dutch permission to build part of their mayoral building – the part delineated by the brightly illuminated border strip running right through the meeting room.

[...]

Given that Belgium’s planning laws are less restrictive than the Netherlands’, there are clear advantages to having a front door in Belgium [...] Kees wanted to redevelop the original building, but the front door was in the Netherlands and he couldn’t get planning permission from the Dutch town hall. He solved the problem by simply installing a second front door, adjacent to the first but on the other side of the border. So now with two front doors to the building, one of his apartments is Dutch, and the other three are Belgian.

[...]

The most flagrant example is a former bank that was built right on top of the border so paperwork could be moved from one side of the building to the other whenever one nationality’s tax inspectors came calling.

Thanks. These towns were mentioned here a lot, but the article is actually on of the longest and most detailed I’ve seen
