fragrances under the name of Eau de Cologne. Giovanni Maria Farina's formula has been produced in Cologne since 1709 by Farina opposite the Jülichplatz and to this day remains a secret. His shop at Obenmarspforten opened in 1709 and is the world's oldest fragrance factory.

Another famous scent, the Original Eau de Cologne 4711, is named after its location at Cologne's Glockengasse No. 4711.
