Memoria y olvido en imaginarios y paisajes urbanos
(Pontificia Universidad Católica del Perú, 2025-12-16) Alvarez-Calderón Silva-Santisteban , Rosabella; Quiroga Robles , Mariano
This essay explores how memory/remembering and oblivion/forgetting shape urban landscapes and collective imaginaries. Throughout history, societies have been molded by oral, written, and artistic traditions, as well as by spatial experiences and perceptions that foster attachments to place. In a continuous feedback process, the presence and absence of memory transform the built environment. Drawing on a comparative perspective between global contexts and two case studies in Lima, an international exposition known as La Feria del Hogar and the La Herradura seaside resort, we examine how memory, or its absence, influences city-making and the ways we imagine urban spaces.

Arquitectos censados en Chile 1865-1895: la expansión de la profesión
(Pontificia Universidad Católica del Perú, 2025-12-16) Inostroza Hernández , Carlos
Architects who practicing in Chile during the second half of the 19th century have been poorly documented due to the scarcity of studies on the subject, which generally focus on emblematic works and relevant positions. According to the national census reports of 1865, 1875, 1885, and 1895, “architect” was among the registered professions, but this statistical background has not been addressed in our disciplinary historiography. Through a quantitative analysis of these results, we have obtained an insight into the universe of architects, their expansion, hierarchical centers in the territory, and groups of foreigners by nationality, which allows us to contribute to the knowledge of the practice of the profession during this period.

Vitalidad urbana y memoria temporal en las calles comerciales de Tokio: un estudio cuantitativo precovid-19
(Pontificia Universidad Católica del Perú, 2025-12-16) Carmelino Hurtado , Giancarlo
This study analyzes urban vitality as a dynamic socio-spatial phenomenon linked to the temporal memory of commercial streets (shōten-gai) in Tokyo, Japan. Based on the quantitative relationship between pedestrian activity and physical elements of the built environment, hierarchical cluster analysis and multiple discriminant analysis were applied to twenty representative cases. Three states of urban vitality were identified (passive, active, and accelerated) defined by hourly variations in variables such as open shops, urban furniture, and signage. The results suggest that vitality does not depend exclusively on permanent architecture, but rather on the everyday repetition of usage patterns and on semi-permanent visual cues that shape a temporal memory of space, making it possible to identify urban conditions favorable to social interaction and local commerce. The manuscript thus presents the implementation of a proprietary and replicable quantitative methodology that allows for observing how certain combinations of variable factors can contribute to differentiating states of urban vitality. It also offers insights for potential future applications as a tool to support design decisions.
