This chapter discusses the creation of imperial cities: Paris was remodelled by Napoleon III, the layout of Vienna was altered in the era of Franz Joseph, and Berlin was expanded under Wilhelm I and Wilhelm II from a Prussian into an imperial capital. In each case this meant creating broad boulevards, green spaces, and impressive buildings, but also providing clean water, efficient sewage systems, street lighting, and local transport. Monuments celebrating victories and generals were also part of the urban design. London only built a ceremonial avenue in the twentieth century. Maximilian had great plans for Mexico City based on what he had seen in Paris, Vienna, and Brussels, while Pedro II built Petrópolis, a summer residence in the hills above Rio de Janeiro.
