Setor Jaó, one of the oldest neighborhoods in Goiânia, is believed to have been designed and constructed in the 1950s by German prisoners of war during their internment in Brazil. This revelation was brought to light by lawyer Arthur Rios, who specializes in real estate law and has represented residents of the area in legal matters. The planning of the neighborhood was carried out by engineer Tristão Pereira da Fonseca, as the German builders lacked proper registration with Brazil's regional engineering council.

The background to this story involves a historical agreement between the Brazilian government under Coimbra Bueno and the British government, which allowed nearly 50 German POWs to work on local construction projects in Goiânia after World War II. Interestingly, the construction was kept relatively quiet to avoid public scrutiny, and the initial intention was to house these prisoners in an old state prison. However, the plan evolved, leading to the development of the neighborhood as we know it today.

This information not only sheds light on the architectural history of Goiânia but also raises questions about the narratives surrounding the treatment of prisoners of war in Brazil. It highlights the post-war dynamics and the engagement of former combatants in civilian projects, indicates the complex legacy of war, and invites reflection on how historical events intertwine with contemporary urban development.
