A growing global tradition is for romantic couples to place a love lock on a bridge and, while warmly embracing, throw the key into the water below. Most European cities consider the padlocks a nuisance but not Helsinki. The city legally approved this expression of everlasting devotion. The most popular spot is at the Bridge of Love. This is a nickname for Rakkauden Silta or Kärlekens Bro. The small pedestrian bridge spans the Vantaa River from center city to the islet of Katajanokka.
