Berlin-based Burkinabé architectural studio Kéré Architecture has unveiled the full design for Biblioteca dos Saberes (The House of Wisdom), an ambitious 40,000-square-meter public library and cultural centre set to become a transformative civic anchor in Rio de Janeiro’s Cidade Nova neighbourhood. Commissioned by the Rio City Hall as part of a broader urban revitalization initiative around Valongo Wharf and the Little Africa district, this project marks the firm’s first built work in South America and its second major library following the acclaimed Gando Primary School Library in Burkina Faso, the hometown of founder Diébédo Francis Kéré.
The library’s site is deeply symbolic and culturally resonant. It sits immediately adjacent to the historic Praça Onze—the birthplace of Brazil’s first samba school—and overlooks Oscar Niemeyer’s Sambódromo, the iconic parade ground pulsating with the energy of the annual Carnival. The location situates the building at the nexus of Rio’s complex cultural layers: Indigenous roots, Afro-Brazilian heritage, samba and carnival traditions, and its legacy as a port city shaped by transatlantic history. This rich context informs the library’s conception as both an architectural landmark and a vibrant cultural statement dedicated to indigenous knowledge, Afro-Brazilian history, oral traditions, and samba as a living, embodied form of knowledge.
At the heart of the design is the library’s defining architectural and symbolic element: a vertical cylindrical volume described by the architects as the “tree of knowledge.” This glowing tower rises through the centre of the complex, inspired both by the native trees of Rio’s Tijuca Forest and by the communal role that trees play in West African villages like Gando, where they serve as gathering places for community dialogue, storytelling, and learning. Serving as the organizational spine of the building, this luminous cylinder connects the three levels of the library, internally linking spaces that progress from quiet study zones to lively public engagement areas. It is a poetic and spatial metaphor that anchors the entire project in both local ecology and cultural memory.
Encircling this central tower, the building unfolds through a series of gently curved planes and elevated pathways, all wrapped in a carefully designed perforated brick façade system. This porous envelope is both aesthetic and functional, responding to Rio’s intense sunlight by mitigating heat gain while admitting filtered light and encouraging cross-ventilation. These sustainable design strategies are hallmarks of Kéré Architecture’s commitment to climate-responsive, contextually attuned architecture. Complementing this, the library features landscaped terraces, shaded courtyards, open-air circulation corridors, rooftop gardens, and a canopied amphitheatre that dissolve the boundary between interior and exterior, inviting the surrounding urban fabric and its inhabitants into daily interaction with the building.
Inside, the program is expansive and carefully calibrated to encourage a diverse range of knowledge practices. The library contains reading rooms and stacks for quiet reflection and scholarship, workshops and exhibition spaces for creative exchange, an auditorium for lectures and cultural performances, and a café that serves as a social hub. Rather than a static repository of books, Biblioteca dos Saberes is designed as a dynamic ecosystem where knowledge is not only stored but lived, shared, performed, and transformed—echoing the rhythms of samba itself, which moves from body to heart in an unbroken chain of expression and community.
A particularly significant architectural gesture is the pedestrian bridge linking the library directly to the nearby Monumento a Zumbi dos Palmares, a monument honoring the leader of Brazil’s historic anti-slavery resistance. This bridge physically and symbolically weaves the library into the ongoing narratives of Afro-Brazilian resilience, identity, and cultural continuity. It positions the library as a vital node within the city’s spatial and historical memory, reaffirming Rio’s commitment to recognizing the contributions and struggles of its Afro-descendant population.
The project was formally presented to the public on November 20, 2025, Brazil’s National Day of Zumbi and Black Consciousness, underlining the library’s role as a civic institution deeply rooted in memory, identity, and empowerment. Rio de Janeiro Mayor Eduardo Paes remarked, “From Little Africa to the world, Francis Kéré’s project pays homage to the Atlantic, African, and portside formations that have shaped this plural Rio … a library of samba and of the people’s wisdom.” His statement elevates the library beyond architecture into a cultural manifesto aligned with Rio’s status as the first Portuguese-speaking UNESCO World Book Capital, a recognition of the city’s vibrant literary culture and commitment to knowledge access.
The design reflects Francis Kéré’s architectural ethos—deeply rooted in community engagement, climate-conscious solutions, and reverence for place and cultural histories. By drawing simultaneously from Brazilian and West African traditions, the project reimagines the Atlantic Ocean not as a dividing line but as a shared corridor of heritage, exchange, and knowledge—a river that connects continents, histories, and futures. The Biblioteca dos Saberes becomes a spatial embodiment of this vision, a cultural bridge between Africa and South America.
More than a public library, Biblioteca dos Saberes promises to be a cultural epicenter: a vibrant space that nurtures learning, fosters social encounter, celebrates diverse heritage, and anchors a broader movement of civic renewal in Rio’s historic downtown. Construction is anticipated soon, and once completed, the building will stand as a lasting testament to how architecture—when thoughtfully conceived and contextually rooted—can become a vessel for collective wisdom, resilience, and transformative public culture.
