We present a vision of the evolution of the solution to the social issue, through state policies focused on the construction of social housing in Valparaiso, noting the uniqueness of modern architecture built in the city, iconic works that have particularities in their proportion, aesthetics and location that make them stand out from other Latin American proposals. From this singularity we propose that the end of an architecture with conviction was provoked by the intrusion of urban land price speculation and consequently the emergence of a market architecture, which abandoned any possible space of singularity.

This article presents a comparison of the current regulatory frameworks on the administration and management of the borders of Peru, Bolivia, and Chile, examining the notion of security in each of them. Differences related to the reading of the role of the border as a control device and the perception of security as a complement to the development of border territories are identified. In methodological terms, techniques referring to the comparative method and content analysis are used, allowing the review and interpretation of the sources consulted. The main conclusions are related to the establishment of security as a valid element in all cases, but qualified by the historical vision and economic reality, so its application circulates between these two conceptions.

This article analyzes the knowledge and appreciation that Chilean military institutions had of Deception Island after World War II, when both whaling activity and territorial ambitions for Antarctica -and its maritime spaces- regained strength. Due to its location, configuration, and tranquil bays, Deception -part of the South Shetland Islands-was considered a good place to establish whaling stations and provide shelter for vessels during harsh weather. However, despite the island’s importance in the mid-20th century, Chilean historiography has paid little attention to it. Although the Army and the Antarctic elite in the late 1940s had considerable knowledge on Deception, it is striking that some institutional publications did not show much interest in studying this topic, or at least in publishing about it.

Recalling the events that would have prompted the governor of Magellan and the Chilean government in 1892 to decide the founding of a town on the northeastern coast of Navarino Island, constitutes the main objective of this work.
