Die Rückkehr der Kühe (The Return of the Cows), Dietrich-Bonhoeffer Strasse 23, Berlin, Germany

In an otherwise ordinary street in Berlin, there is an extraordinary art installation. On the side of a pre-war Berlin apartment building, larger-than-life cows walk up and down a green field. Artist Sergej Dott created this unusual sight, which is one of what he terms “Kuhunst,” a pun based on the German for art (Kunst) and the word for cow (Kuh).
