Organised by the International Union of Architects (UIA) since 1948, the World Congress of Architects will be held for the first time in Brazil.

This is a unique meeting place for professionals and future leaders in Architecture and related fields: an event discussing the future of cities and the city of the future.

Leading names in architecture and urban planning will gather together to analyse the global outlook and local issues, drawing up proposals and presenting solutions for enhancing the quality of life, in a fairer and more sustainable world.

All the worlds. Just one world. Architecture 21

A meeting of generations that will go down in history

Architects from every continent, ranging from renowned names to new talents, practitioners, researchers and thinkers about urban environments, students, builders, social movements, technology and innovation companies, academic and multilateral institutions, political entities, all are invited to share experiences related to constructing the spaces where social life takes place.

The public health crisis currently sweeping the world has highlighted the interdependence of economics, politics, society, the environment, and the city. Like a premonition, this interdependence was underscored in the theme of the 27th World Congress of Architects. More than ever, it is vital to understand that we are living in the same era and sharing the same planet.

There is a good likelihood that this calamity will give rise to City 21: aware of the environment and the climate, seeking good spaces, lessening intra-urban inequalities and focused on citizens.

Paulo Mendes da Rocha

The Brazilian who won the Pritzker Prize 2006.

Rio de Janeiro and Architecture

Selected to host the 27th World Congress of Architects, Rio de Janeiro was also awarded the new title of World Capital of Architecture by UNESCO and the UIA.

Architectural landmarks covering five centuries – like the Palácio Capanema and the Museum of Modern Art – are clustered in the historic heart of the city, where UIA2021RIO will be held.

In addition to its architectural heritage framed by breath-taking landscapes, Rio is also a city of challenging contrasts and notable diversity. A living open laboratory, it is the perfect setting for global studies of metropolitan challenges.

The main events scheduled for UIA2021RIO, including the Opening Ceremony, will be held in the historic downtown area of Rio de Janeiro. Among many other attractions, some of the city’s most famous buildings are clustered here, representing architectural styles that range from colonial to contemporary.

The main venue for UIA2021RIO is the Pier Mauá: a cluster of old port warehouses that have been revitalised and today form an area well-equipped to host major events.
