How To Divide States
The Netherlands is situated alongside the North Sea in the northwest and Germany to the east, with Belgium to the south. Without the security of its dunes and dikes, this populated region of the country would be submerged, primarily due to the ocean but also from the rivers.
The European nation is also comprised of several states, and while we mostly see structures in borders, this country only has pavement markings such as these in the picture. This shows the border of Baarle-Nassau and Belgium, and because some of the houses run through the lines, there are many homeowners who have a house in both places!
