The current Belgian-Dutch border was laid down in detail and established officially in 1843. 388 cast-iron border posts were installed along the border. Each post was embossed with the Belgian Lion on one side and the Dutch Lion with a sword and arrows on the other side. Each post has a number, going from 1 at the place where the Netherlands, Germany and Belgium meet in Vaals up to 369 in Zeeland Flanders. Almost all posts have the year 1843 on them.
