Unique State Boundaries
The Netherlands is situated alongside the North Sea in the northwest, Germany to the east, and 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, many homeowners have a home in both places!
