In the complex task of preserving Visual Arts collections, the role of environmental factors is paramount, notably within the distinct Amazon climate. This article examines the environmental elements crucial for conserving Visual Arts collections, focusing on the external environment, macroenvironment, and microenvironment's interplay. It centers on the Contemporary Art collection of Casa das Onze Janelas in Belém do Pará as the primary subject. The aim is to foster critical analysis and offer insights into the preservation challenges of this collection in the Amazonian climate. The methodology involved collecting data over three months from two protective environments, utilizing three dataloggers (models HT-70 and HT-900), and meteorological stations for external environmental data. This data was then juxtaposed with contemporary literature in the field, thereby augmenting our analysis with the latest scholarly insights. Preliminary results from the Provisional Technical Reserve indicated an average temperature of 23.72°C and a relative humidity of 69.37%, with the microenvironment showing a slight variation (24.10°C temperature, 63.10% humidity). The Visual Arts Reserve recorded an average temperature of 24.33°C and humidity of 70.92%, whereas its microenvironment presented averages of 26.11°C and 71.46% humidity.
