Rio de Janeiro has just landed a big date on the global calendar. The Rio architecture forum of 2028 will bring thousands of designers, planners and tourism officials to the city for a week of debate about how crowded cities can grow without wrecking what makes them special.

The decision was made on Sunday, July fifth, at the Disseny Hub in Barcelona, Spain, according to the Rio de Janeiro city government. Rio was picked by acclamation, meaning delegates agreed without a contested ballot, to stage the fifth International Forum of the International Union of Architects.

The International Union of Architects, usually shortened to its French initials UIA, is the worldwide umbrella body for national architecture associations. Its forums gather professionals, researchers, students and government planners to compare notes on how cities are built and lived in.

Why this Rio architecture forum matters

For the first time, the forum will be held somewhere in the Americas. Every previous edition took place elsewhere, so 2028 marks a genuine debut for the whole region, not just for Brazil.

Organisers at the Institute of Architects of Brazil, the country’s main professional body for the field, expect more than five thousand people to attend in person. Thousands more are meant to join free events open to the general public.

The gathering pulls in a broad crowd, from famous designers to students, alongside public planners and people who work in tourism. That mix is part of the appeal, since the meetings are meant to be as much about policy and city management as about buildings themselves.

The bid ran under the motto “One city, many worlds,” a nod to the mix of neighbourhoods, landscapes and social realities packed into one sprawling metropolis. Mayor Eduardo Cavaliere called the choice a source of great pride that confirms the city’s role in debates about the future of large urban centres.

He added that hosting the meeting in 2028 would be a rare chance to share the city’s experiences with specialists from around the world and to build partnerships. City officials cast the win as proof that Rio is ready to lead, rather than merely follow, global discussions on urban life.

Frequently Asked Questions

How is the forum linked to a UNESCO tourism title?

The forum is tied to a larger ambition. Winning it is described by the organisers as a decisive step toward a brand-new honour, the title of World Capital of Sustainable Tourism, created jointly by UNESCO and the architects’ union.

Marcela Abla, who heads the institute’s Rio chapter, framed the event as a chance to show how balanced urban policy can pair tourism and economic growth with the care of heritage and nature. The bid drew backing from the federal government, the state culture department and bodies such as UN-Habitat, the Oscar Niemeyer Foundation and the Burle Marx Institute.

What does the Rio architecture forum mean for residents?

For anyone living in or planning a move to Rio, an event of this size two years out is worth noting early. Large international gatherings tend to lift hotel demand, tighten short-term rental supply and speed up work on transport and public spaces.

The 2028 date also slots into a busy run of global meetings the city has courted, from climate summits to sporting fixtures. Taken together, they point to a Rio that keeps positioning itself as a stage for the world’s conversations about how people should live in cities.

The bid leaned heavily on the city’s architectural heritage, from the modernist landmarks of the historic centre to the tropical gardens designed by Roberto Burle Marx. For newcomers, that heritage is part of everyday life rather than a museum piece, woven through the districts where many foreign residents settle.

There is also a practical read for the property market. Cities that win recurring global events often see targeted upgrades to waterfronts, transit lines and cultural venues, changes that can reshape which neighbourhoods feel liveable and where rents drift over the following years.

When and where will the event take place?

The forum is scheduled for 2028 in Rio de Janeiro, though a precise venue and dates have not yet been confirmed. The winning bid was formally announced in Barcelona in July 2026, roughly two years ahead.
