4711 is a traditional German Eau de Cologne by Mäurer & Wirtz. Because it has been produced in Cologne since at least 1799, it is allowed to use the geographical indication Original Eau de Cologne. The brand has been expanded to various other perfumes and products besides the original Echt Kölnisch Wasser, which has used the same formula for more than 200 years. The 4711-flagship store in the Cologne Glockengasse is a popular tourist attraction.
