Continuing a series of architectural guides dedicated to projects in Portugal that already includes Aires Mateus, Alvaro Siza, Eduardo Souto de Moura, and Carrilho da Graca, this next instalment embarks on a journey throughout the country to document works by Goncalo Byrne. He started his career after graduating from the Lisbon School of Fine Arts in 1968, a time marked by protests and a shift towards modernisation, rationalisation, and effective accountability in the field of Portuguese architecture. Byrne is known for producing designs in diverse scales and functions; in this guide, numerous examples are presented in drawings, photographs, and detailed texts.
