This elegant vessel expresses both the Olympic pride of Barcelona in 1992 and the proletarian dignity of an industrial enclave. Used for professional basketball practice, and as the headquarters of a mythical local team, the building assumes a leading role as a new point of reference in a heterogeneous and undefined urban environment. Two structures are discerned in the oval-shaped floor, which opens in one of its extremes to create the monumental entrance of a stepped plaza. One encloses the great central space and the other organizes the entrances and circulation of the perimeter. The industrial roof with a serrated profile is resolved with six great box beams connected by a longitudinal rib. Evoking the interiors of old cathedrals, the structural framework lends luminous solemnity to the liturgy of sports practice.
