Cologne is the fourth biggest city in Germany and is the largest in the German federal State of North Rhine- Westphalia. It lays besides the River Rhine. The first love locks appeared in 2008 in the city. For many years now these padlocks have been considered as one of the most charming traditions. Now the padlocks’ weight is estimated over two tonnes. The Hohenzollern Bridge spans the Rhine, and its railings offer a home for the symbols of love. Visit Cologne, join other couples’ tradition and attach your padlock as well!
