This research investigates spatial formations of the People's Square of Shanghai from the 1840s to the 2000s against a shifting history of political and ideological backdrops. The research explores how the Square was formed and reformed, how it was used, how it facilitated and restricted certain social uses, and how it both reflected and subverted, to an extent, a predominant political and ideological control. The thesis reveals new layers of spatial politics of the Square and adds new dimensions to our reading of the meaning of the city centre of the Chinese metropolis.
