Alvaro Siza is considered one of the most important Portuguese architects of the 20th century, and his works have garnered praise far beyond the borders of his own country. In 1992 he was awarded the Pritzker Prize for his life's work. The Museum of Architecture he founded together with Rudolf Finsterwalder on the Island of Hombroich is a major attraction for visitors, and received a "Brick '10" (Wienerberger Brick Award) in 2010. The new exhibition on the works of Siza, which will open June 17 on Hombroich, primarily presents little-known material on some of his more famous projects: sketches and models, accompanied by large-format photographs, serve to make Siza's working methods palpable and real. The catalogue, which focuses on 10 selected projects, was conceived as a reserved and straightforward, yet nonetheless bibliophile-friendly book offering those familiar with Siza new insights into how he works.
