Philips-Zeiss-Werk

Philips-Zeiss-Werk is a factory building with a distinctive observatory dome on its hilltop location in Penzing, originally designed for manufacturing and testing optical instruments. The structure combines production halls with scientific testing spaces and was built in reinforced concrete following Robert Oerley's design.

The building was constructed in 1916-1917 initially as a production facility for Zeiss optical devices, but sat unused for over a decade after 1918. Following its reactivation, it became a radio factory and later marked a milestone in electronics when producing the first Philips tape recorder in 1947.

The factory represents Vienna's position as a center for optical and electronics manufacturing in the 20th century. The distinctive dome on the hilltop was not just functional but also symbolized the city's commitment to technical innovation.

The building is located in western Vienna's Penzing district and is easily visible from outside, with its distinctive dome being particularly striking. Since it now serves as a training facility for the Austrian military, visitor access is limited, and it is best appreciated from outside or from a distance.

The building returned to use after nearly 13 years of standing empty during the 1920s, requiring a complete shift in production. This transformation from optical manufacturing to radio production demonstrates how factories adapted after World War I to survive economically.
