Question: Where is the headquarter of  German airline Germania?
Context: The concept of Germany as a distinct region in central Europe can be traced to Roman commander Julius Caesar, who referred to the unconquered area east of the Rhine as "Germania", thus distinguishing it from Gaul (France), which he had conquered.  The victory of the Germanic tribes in the Battle of the Teutoburg Forest (AD 9) prevented annexation by the Roman Empire, although the Roman provinces of Germania Superior and Germania Inferior were established along the Rhine.  Following the Fall of the Western Roman Empire, the Franks conquered the other West Germanic tribes.  When the Frankish Empire was divided among Charlemagne's heirs in 843, the eastern part became East Francia.  In 962, Otto I became the first emperor of the Holy Roman Empire, the medieval German state. The Germania Club Building, located at 108 W.

The upper stories feature arched windows capped by pediments and a pilaster supporting the cornice atop the building.  The building includes a grand ballroom, banquet room, and restaurant and bar.
