A key precedent for expressive structural rationalism and sculptural concrete forms, demonstrating how curved concrete ribs can define both the structural envelope and the symbolic identity of a civic monument.
- What we like about this project
- The bell tower's base flares outward in a direct geometric dialogue with the cathedral's sweeping ribs.

- Geometry
- Hyperboloid structure composed of 16 curved concrete columns that converge toward a central ring before flaring outward; paired with a separate, sculptural concrete bell tower featuring a flared base and a horizontal beam holding four bells.
- Facade system
- Glazed triangular panels infilling the spaces between structural concrete ribs.
- Structural guess
- Hyperboloid concrete frame acting as both primary structure and architectural envelope.
- Spatial scale
- Monumental civic scale, with the cathedral and bell tower rising several stories high above the pedestrian plaza.
- Lighting
- Bright, direct daylight casting sharp shadows that accentuate the deep, curved profiles of the concrete ribs.
- Atmosphere
- A dramatic, sun-drenched civic space defined by stark white concrete forms contrasting against a deep blue sky.
- Environmental context
- Set on a vast, flat public plaza in Brasilia under an expansive blue sky with scattered low clouds.
- Spatial experience
- The building sits on an open, paved plaza, reading as a monumental, sculptural object rising directly from the ground against the sky.
- Composition rhythm
- The repeating, radial rhythm of the curved concrete columns creates a dynamic upward sweep, mirrored by the singular, flared verticality of the adjacent bell tower.
