A historical analysis of color use in Quito's Historic Center reveals that the city's architectural polychromy was significantly diminished by a 1960s municipal ordinance mandating white and indigo blue facades, which bore little resemblance to the diverse color palettes used across different periods. Research conducted by the Gitty Institute at the end of the 20th century demonstrated that Quito's chromatic diversity varied historically due to pigment availability. Despite a recent 'recovery of color' initiative aimed at restoring this diversity, the long-standing ordinance has fostered public ignorance about the city's rich color history. This study underscores the importance of acknowledging and preserving the spatial coexistence of architectural styles from different eras.

A significant portion of the Peralada Palace Library, one of Catalonia's most notable collections, was preserved through the legacy of D. Pedro Antonio de Aragón (1611-1690) to Poblet Monastery. This library, assembled by the Rocabertí brothers, remained intact at Poblet for over two centuries before being confiscated during Spain's Liberal Triennium (1820-1823). The study sheds light on this historical collection, detailing its significance and the devastating impact of the Desamortización Law, which led to the spoilage or dispersal of a substantial part of its holdings. The research methodically catalogs and analyzes the surviving books, offering insights into the library's composition and its cultural importance.

A rigorous analysis of the dukes of Medinaceli's palaces in 18th-century Madrid reveals previously overlooked details about their prominence and architectural significance near the Paseo del Prado. The study clarifies the distinction between two notable properties—one on Carrera de San Jerónimo, considered the duke's main residence, and another known as the palace of the marqués de Cogolludo—and corrects historical misconceptions about adjacent structures. By synthesizing scattered archival records, it provides a nuanced understanding of how these palaces shaped the urban landscape during a pivotal period in Madrid's development.
