As a response to the 2016 Venice Architecture Biennale's challenging theme, Portugal presented a site-specific pavilion on the island of Giudecca. The pavilion exhibited four notable works by Álvaro Siza on Social Housing, revealing his peculiar understanding of the European city and citizenship. Those projects have created true places of neighbourhood, an important subject of the current European political agenda, towards a more tolerant and multicultural society. This book reveals the curatorial experience that supported the display of those works in the Venice Biennale, including unusual images of Álvaro Siza’s recent visits to those four neighbourhoods; but also the major social and urban changes which took place in there: processes triggered by immigration, ghettoization, gentrification and “touristification” of cities.
