Is the city Metropolis concrete or abstract?

The city of Metropolis can be viewed as both concrete and abstract. Concrete, in the sense that it represents a physical place often depicted in comics and media, characterized by its skyscrapers and urban environment. However, it also holds abstract qualities, symbolizing the ideals of progress, heroism, and the complexities of urban life. Thus, Metropolis embodies both tangible and intangible elements.
