The characteristics of Great Cultural Projects and their impact on architectural and urban heritage (1850–2012)

open access: yesArte, Individuo y Sociedad, 2021
This study examines Great Cultural Projects (GCPs) as an element of the developmental process of cities. For this study, GCPs are regarded as a global phenomenon rather than cases that must be analyzed independently.
