The Arsenal is a former military complex of buildings in the south-east of Vienna in the third district.
Several brick buildings in a rectangle layout make up the complex which is located on a bank south of the Landstraßer Gürtel. It is the most distinguished building group of Romantic historicism in Vienna and was constructed in Italian-medieval and Byzantine-Islamic style. Essentially the complex is still preserved in its original form; only a few workshop buildings within the courtyard have been replaced.
