This paper is an effort to examine, through a back and forth excursion in space and time, a particular form of spatial expansion, landed capital, with the goal of enhancing our understanding of its most recent episodes in the production of Cairo's urban spaces. Building on the assumption that there is a relationship between the movement of capitalism and the city forming processes, I shall investigate how the incorporation of the Egyptian economy into the world capitalist, global economy affected the production of the spaces of two selected real estate developments. These two developments, namely, Heliopolis and Dreamland, represent two different epochs in the 20th century, or two different stages in the history of space-commodification in the city. While the former was one of the landed capital's earliest fruits in Cairo, the latter is one of its latest fads. Moreover, by extending the insights of some selected social theorists I shall to interpret the notion of authenticity as it is expressed in the architecture of both developments.
