María Barceló

19th-century Peruvian architect who broke gender barriers to design iconic Andean structures

María Barceló (1820–1895) was an extraordinary figure in South American architectural history, the first known female architect in Peru and a pioneer in Andean building design. Born in Arequipa to a family of builders, she learned construction techniques from her father and grandfather, eventually taking over their business after their deaths. Her work blended colonial Spanish styles with indigenous Quechua influences, creating structures that harmonized with the Andean landscape.

Her most celebrated work is the Basilica Cathedral of Arequipa (1844), where she oversaw the restoration after an earthquake. She added earthquake-resistant features using local sillar stone, a white volcanic rock abundant in the region. Her design for the Santa Catalina Monastery's cloisters (1850s) incorporated innovative ventilation systems and light wells, reflecting her deep understanding of Andean climatic needs.

Barceló defied societal norms by managing major public projects during a time when women were excluded from professional fields. She designed fortifications, bridges, and government buildings, often signing contracts under her own name despite opposition. Her work on the Arequipa Mint (1863) showcased her mastery of functional design and decorative detailing.

Her legacy endures in Arequipa's historic center, a UNESCO World Heritage Site. The María Barceló Cultural Center now preserves her drawings and tools. Modern architects praise her use of local materials and integration of indigenous techniques, which predated current sustainability trends by over a century.
