This thesis explores the enduring presence and continuous renovation of colonial structures from an spatial lens in the context of La Paz-El Alto, Bolivia. By integrating Silvia Rivera Cusicanqui's decolonial thought with Latin American urban historiography and a chronological socio-spatial analysis of La Paz-El Alto, this study demonstrates how historical colonial dynamics persistently shape urbanization processes. The research reveals that the urbanization of La Paz-El Alto is a material manifestation of internal colonialism, where mechanisms of cultural disciplining and exclusion, initially established during the formal colonial period, have been continuously repurposed throughout history. Reforms aimed at "civilizing" and "modernizing" the country triggered massive rural-urban migration and unprecedented urban growth.
