The boundary between peace and war was literally put under tension during the First World War. This walk takes you past influential locations at the time of WWI. You pass the new and old town hall of Baarle-Hertog, the former Belgian post office and the headquarters of the Dutch commander. But also the town hall of Baarle-Nassau, the former train station, the locations of the Belgian military broadcasting station and the soldiers' barracks on Loveren. There was the gate at the fence around Baarle center, the Red Cross post of the Dutch army and several other places that remind of WW1. Never before has a border made such a big difference.
