An advertising column or Morris column (French: colonne Morris, German: Litfaßsäule) is a cylindrical outdoor sidewalk structure with a characteristic style that is used for advertising and other purposes.
They were originally built by La Société Fermière des Colonnes Morris.
On 5 December 1854, after years of proceedings, Berlin's chief of police, Karl Ludwig von Hinkeldey authorized Litfaß' Annoncier-Säulen.
Some are motorized and rotate very slowly, and others house Sanisettes or telephone booths.
In 2017, anti-pollution Morris columns were tested in Paris; they contained materials which filter out particles from the air in order to mitigate carbon dioxide pollution.
