Rio de Janeiro, in Brazil, will be this year’s host of the 27th World Congress of Architects, the most important event in the sector, in which more than 20,000 participants are estimated. Between the 19th and the 23rd of July, and 42 years later, the event returns to a Latin American country under the slogan "All the Worlds. Just One World.” The congress will address the relationship between architecture, construction, housing, infrastructure, mobility, urbanism, urban planning and city management. Cultural diversity, social transformations, inequalities and migration flows will be the four thematic axes of the event.
