'Bota-Abaixo': The shattered facades and the hidden truths of Rio's great demolition

At the dawn of the 20th century, Rio de Janeiro was desperate to shed its colonial skin. To the eyes of the global elite, the Brazilian capital was a dangerous "foreigners' cemetery," plagued by yellow fever, smallpox, and malaria. The narrow, winding alleys inherited from the

Portuguese era were viewed by mid-19th-century hygienists not as historical heritage, but as chaotic blocks blocking sunlight and trapping disease. The response from the newly established Republic was radical: a total architectural and social cleansing.

In 1902, President Rodrigues Alves appointed engineer Francisco Pereira Passos as mayor of the Federal District, granting him unprecedented, autocratic powers. Backed by a suspended Municipal Council, Passos launched a modernization campaign heavily inspired by Baron Haussmann’s sweeping transformation of Paris. The center of Rio became a massive construction zone, an era coined by the population as the "Bota-Abaixo" (the Great Demolition).

In a matter of years, the historic fabric of the city was shattered by the "frenzy of the regenerating pickaxes," as poet Olavo Bilac described it. To cut open the monumental Avenida Central (now Avenida Rio Branco) and modernize the port, anywhere between 700 and 3,000 buildings - including historic townhouses, warehouses, and densely packed tenements - were completely flattened.

On the surface, the dream of a tropical Paris was realized. The elite filled their salons with French dialogue, abandoned coffee in favor of 5 PM tea, and paraded down wide avenues decorated with electric lighting and eclectic facades. However, this new reality functioned largely as an urban theater - a "theatrical scenography," as the biting critique of writer Lima Barreto put it, which divided the city into a wealthy European bubble and an impoverished native reality.

The human cost was devastating. The working-class poor, who relied on the city center for their livelihoods, were violently displaced. With no affordable housing provided by the state, thousands were forced to disperse to distant train suburbs or claim the nearby steep hillsides. This massive displacement directly accelerated the birth of Rio’s first favelas, such as Morro da Providência, where displaced tenants joined soldiers returning from the Canudos campaign.

This forced purity was even engineered into the visual memory of the era. The municipality hired the master photographer Marc Ferrez to document the brand-new Avenida Central. To project an image of absolute order to the world, the final prints were artificially cropped. Any evidence of ongoing construction, lingering rubble, scaffolding, or the actual hands of the construction workers were mechanically erased from the official album. The elite operated on the strict logic that what the eye could not see in the frame did not exist.

Today, walking through the Historic Center of Rio is an exercise in urban archaeology. Beneath the grand structures of the early 1900s lie the silent memories of a city broken by marring pickaxes. For the curious traveler, true luxury is not found in the artificial symmetry of a postcard, but in discovering the hidden, narrow passages and resilient cultural enclaves that refused to be swept away by the authoritarian tide of progress.

At Taste Rio Tours, we guide you through these living historical contradictions, showing that Rio’s true soul always belonged to the vibrant culture that survived beneath the grand theater of the elite.
