The Union-Theater was a large cinema located on the Alexanderplatz in the German capital Berlin. Opened in 1909 it was the first of a chain of cinemas built by the German film magnate Paul Davidson. Equipped with an orchestra to accompany the action on screen, it provided a model for numerous subsequent film palaces across the German Empire.[1] In 1913 Davidson had it remodelled and expanded its capacity to 1,200 seats, at that time the largest in the country.[2] It hosted a number of premieres of new films, both German and foreign imports.
Like the rest of Davidson's cinemas, it was subsequently taken over by the large UFA concern.
