While strolling through the cozy Vila Nery neighborhood in São Carlos, it's impossible to pass by the unusual monument known as the Tram Balloon – Praça ARCESP. This site, officially named Praça ARCESP, is a historic traffic circle that served as an important point on the tram route during the first half of the 20th century.

The centerpiece of this architectural ensemble is a magnificently preserved historic tram of Belgian manufacture. For five decades, this nine-ton giant was a vital part of city life, and it has now been transformed into a unique open-air monument symbolizing the technical progress Brazil was experiencing during those years.
The square is equipped with benches and surrounded by shade trees, making it not just a historical site but also a pleasant place to relax. The tram is protected by a special glass barrier, inside of which are information panels featuring archival photographs and facts about the city's transport system, turning a simple walk into an educational excursion.
