Baarle is one of the strangest places on the map of Europe. The Dutch municipality of Baarle-Nassau and the Belgian municipality of Baarle-Hertog are so tangled together that the border between the Netherlands and Belgium runs in and out of the town in a series of loops, with Belgian territory in islands within Dutch land, and in a few cases Dutch islands within the Belgian ones. Seen on a map, the pattern resembles a scattering of irregular patches, and the boundary even runs through the middle of some streets, houses and shops.

The origin of this oddity lies in the Middle Ages. In the twelfth century, the land around Baarle was divided between local lords and the Duke of Brabant through a series of feudal agreements and exchanges, and the rights to particular parcels passed to different owners over time. When the modern border between the northern and southern Low Countries was drawn in the nineteenth century, after the Belgian revolution, the diplomats found the situation so complicated that they left the ownership of each parcel as it stood. The result is a patchwork of around two dozen Belgian pieces within the Netherlands and a few Dutch ones inside those.

Visitors can walk the border lines, which are marked on the pavement with white crosses and lines, and numbering on house fronts shows which country a building belongs to. The Belgian and Dutch flags hang beside doors, and in some places a house has its front door in one country and its back garden in another. The rule is that the country in which the front door lies determines the nationality of the house, which led to cases where residents moved their doors to choose their country, for example for tax reasons. The tourist office provides a map and a walking route.

The local oddities extend to everyday life. Streets can have two sets of postal services, two police forces and two sets of rules, for instance about shop opening hours and fireworks, and the effect can be confusing but also amusing. Restaurants and cafes sit on the border, and some have a line running across the dining room, so that you can eat with one foot in each country.

Baarle suits curious travellers, families and anyone who enjoys geographic trivia. Allow a couple of hours, take the walking route and stop for a coffee or a Belgian beer. Bring ID if travelling, though the border is open.
