This etching was likely created when Pollak was employed as an artist by the Austrian Army to chronicle World War I. He would base several early etchings on his wartime observations.
The structure was located in Weigl's Dreher Park, Vienna. It was an indoor ampitheater built for the International Music and Theater Exhibition in 1892, and could hold 4,000 occupants. It changed hands several times but was always a place of entertainment and was in service through 1925, when it was demolished.
In this image, Pollak illustrates one of the building's brief but necessary transformations: as Reserve Hospital Number 4, an auxiliary unit for wounded soldiers of World War I in 1918. Hospital beds are arranged, row after row, on the floor that in peaceful times was meant for dining and dancing. Hospital workers watch over them from the upper balcony.
