Luxembourg, Vatican City, Monaco, San Marino, Singapore, Baarle-Hertog / Baarle-Nassau, Neutral Moresnet, Malta, Gibraltar. I love-love-love microstates, small nations and other quirks of geopolitical history.
After Baarle-Hertog / Baarle-Nassau, Oriol and I drove to the Vaalserberg in Limburg, where Kingdom of the Netherlands meet the Kingdom of Belgium and the Federal Republic of Germany. It’s commonly known as Drielandenpunt, Point Trifrontières or Point des Trois Frontières and Dreiländereck. It used to be a quadripoint with Neutral Moresnet.
