Since 2020, Carla Cruz and Claudia Lopes have been developing a joint reflection on the notion of time and the relatively ephemeral relationship we have with it, in contrast to the persistence of objects, places, and geologies. Their projects manifest themes such as circularity, fragmentation, sedimentations, landscapes—natural, constructed, transformed, and fictional—as well as crossed temporalities, ends of the world, and other speculative prefigurations. These are simultaneously plastic and conceptual, in a shared interest in moldable and organic materials and non-urban affective territories. Between 2021 and 2023, they participated in an exploratory project in the Regoufe tungsten mines, which had been inactive for almost 75 years, resulting in exhibitions (“Pedras” at the Arouca Monastery and Trilobite Museum; “Escombreiras” at the Ferreira da Silva Laboratory, Porto) and publications (“Medula” and “Escombreiras” i2ADS). In 2021 they held the solo exhibition “Sedimentos” at the Júlio Dinis House Museum, Ovar; in 2023 the solo exhibition “Superfície” at the Extéril Gallery, Porto and the solo exhibition “Inerte” at Espaço UM in Guimarães; in 2024 “do subterrâneo” exhibition at the Nuno Centeno Gallery, Porto and they participated with the installation “Superfície” in the Trás-os-Montes Biennial in Macedo de Cavaleiros; in 2025 they conceived the performance “Ar” in residence at the Maceira School and presented at the Maia Biennial 2025; and also the solo exhibition “Gramáticas Pardas”, curated by Ana Anacleto, at CAAA – Guimarães.
