Tabakregie/ HTL Ottakring, Former tobacco factory and technical school in Ottakring, Vienna, Austria

Tabakregie is a large factory complex at Thaliastraße with multiple buildings designed in Neo-Renaissance style that reflect its industrial past. The main structure now houses classrooms and workshops for a technical school.

Construction of the factory began in 1893 and was completed in 1898, making it the second factory of the imperial-royal Austrian Tobacco Directorate. Built by engineer Karl Stigler, it produced cigars, smoking tobacco and cigarettes; by 1913 output reached 33 million cigars and 133 million cigarettes. Production ceased in the late 1990s, and in 1999 the HTL Schellinggasse school moved into the main building.

The site now functions as a technical school, maintaining its role as a place where skilled work takes place. Students use the spaces for hands-on training, giving the original production function a contemporary purpose.

The site is well served by public transit, with a tram stop nearby making it accessible from across Vienna. Since the buildings are used as a school, visiting outside class hours or arranging in advance is recommended.

The site's own power station stood in the middle side wing: a steam boiler and engine plant with a dynamo and auxiliary equipment supplied the factory's electricity. A narrow-gauge tow railway handled deliveries and dispatch, and roller tracks ran through the side courtyards. The drying of cigar fillers used steam-heated cells fed with pre-warmed outside air and connected to exhaustor-driven extraction ducts.
