The world is not always what we think it is. This book presents unusual borders, enclaves and exclaves, divided or non-existent cities and islands. Numerous conflicts have left countries divided and often shattered. Remnants of countries can by design or accident be left behind as a legal anomaly in this complex world.

Most people believe that a country’s borders are clearly defined: just lines that separate countries. Everything on one side of the line belongs to one country and everything on the other side belongs to another country. This might be the case most of the time, but there are unusual exceptions to this unwritten rule.
