Green Week traditionally takes place at the beginning of the year in the Messe Berlin exhibition halls under the Funkturm and is open to the general public.
[citation needed] The first green week (not yet "international") was held from 20 to 28 February 1926, when an employee at the Berlin Tourism Office had the idea to combine the traditional winter meeting of the German Agricultural Society with an agricultural exhibition as a secondary showcase for fair participants.
Green Week took place every year until 1939, with the exception of 1938 because of an outbreak of European foot-and-mouth disease.
After a break in 1951 due to major postwar construction, the fair was held again in 1951 and every year since.
Special shows on topics such as "German Cheese" and since 2005 a technical program of over 250 lectures, seminars and symposia round off the exhibition.
