Around 250 people marched from the French town of Apach to Schengen, passing through the German town of Perl, in a demonstration against border controls.
The protest was organised by the pro-European political party Volt, which argues that controls at the German and French borders undermine European solidarity.
According to Volt, these measures represent a setback for European integration. In response, the party called for demonstrations advocating for open borders.
After marching through the tri-border area, participants gathered at the Schengen Agreement Monument where speeches were delivered.
