This exhibition highlights key periods in the history of Bon Pastor, a neighborhood that exemplifies the evolution of housing and social cohesion in the city throughout the 20th century. Through the restoration and presentation of four social housing units, visitors gain insight into the neighborhood's journey from 1929 to 2010, concluding with a brief update until 2022. Each unit reflects a distinct era that marks significant changes in the community’s experience: scarcity during the early years, post-war development, transformative reforms, and the rethinking of housing policies. The display incorporates thematic audiovisual capsules featuring firsthand accounts and corroborated documents, emphasizing historical accuracy and archaeological research. Additionally, the exhibition includes the documentary 'Bon Pastor: A Century of Barcelona' and a collection of planning documents featured in a multifunctional space.
