The research focuses on the individual and collective memory, the connection and the investigation of her relationship with space and architecture. Some of the questions that arise are whether her architectural projection is associated with the surrounding cultural principles, what we define as a monument today, if the city could be approached as one, how the city's parts could be explored about their monumentality, with an open approach to the limits of the conventional answers could be given. A brief retrospection of selected points and references from ancient times until today is presented, regarding the relationship of memory with place and architecture and specific tactics in the city's evolution and her elements such as monuments. The retrospection presents references to characteristics such as form, symbolism, design, etc. The case studies investigated, aim to explore these characteristics through the work of the architects Aldo Rossi, Denise Scott Brown, Robert Venturi and Rem Koolhaas. In each one of the case studies, are identified different strategies marking architectural commemoration. In the case of Aldo Rossi, the strategy points out the systematic study of the history of the city and the concentration of memory and communities of the emergence of a typology. In Learning from Las Vegas, of Denise Scott Brown, Robert Venturi and Steven Izenour, through the study of Las Vegas, its existing architecture, aesthetics of the everyday and the symbols that identify this, observations and recommendations expressing society of the time are produced. Similarly, through Rem Koolhaas's study of Manhattan, the existing form of the city is again presented and studied, the American skyscraper is pointed out as basic typology of the city and through him arises a theoretical approach about skyscraper's and city's monumentality, which is enriched through the project The City of Captive Globe.
