Construcción vacía-Eraikuntza hutsa, Steel sculpture in Pasealeku Berria, Donostia, Spain.

Construcción vacía-Eraikuntza hutsa is a steel construction made of several angular pieces that intersect and frame empty space. The parts stand together without fully connecting, creating a visual dialogue between solid material and the space between them.

Jorge Oteiza's steel sculpture won the prize at the 1957 São Paulo Biennial, and the piece was installed on Pasealeku Berria in 2002. The spot had earlier held a chapel and a monument to the victims of the cruiser Baleares, a Nationalist ship sunk in 1938. The chapel, dedicated to Our Lady of Mount Carmel, was a Francoist construction.

The sculpture's Basque name, Eraikuntza Hutsa, means "empty construction", pointing to Oteiza's aim of shaping void rather than mass. It stands on Pasealeku Berria, a promenade in Donostia, and won the sculpture prize at the 1957 São Paulo Biennial before being placed here in 2002.

The sculpture is accessible year-round in an open public space and requires no special preparation to visit. You can walk around it and view it from different angles to understand how the forms relate to each other and the surrounding area.

The steel pieces were arranged so they nearly touch but never fully connect, which gives the work its name Construcción vacía. This intentional gap between elements allows viewers to discover emptiness itself as a design choice rather than an accident.
