A historical view of our present premises. The building itself was erected in 1929 and soon several Faculties of the Poznan University were moved into it. During the Second World War it was transformed into Luftwaffe Headquarters by the German occupants, and hence bombed by Americans in 1944. In this photograph, made by Michal Zenkteler in 1946, a group of students of the Forestry Department clear the debris in 1946. Our laboratory in located on the first floor right behind of the group of students and the cart. In 1975 these rooms were adapted by Prof. Zygmunt Kaluski (1920-1993) for the Crystal Chemistry Laboratory.
