In celebration of Barcelona's designation as the World Capital of Architecture in 2026 by UNESCO-UIA, the city council launched an international competition in June 2024 inviting young architects from around the globe to transform the party walls across its ten districts. The exhibition 'From Party Walls to Facades: A Legacy for the City' showcases the finalist and winning designs, highlighting the evolution of these architectural proposals aimed at reimagining these structures into engaging facades. This initiative not only enhances the urban landscape but also creates a dialogue about architectural innovation and community identity, allowing visitors to appreciate how contemporary architecture can reflect and enrich the historical fabric of Barcelona while providing new aesthetic and functional possibilities for its public spaces.
