Cristina Iglesias has designed a site-specific piece for the Botín Centre and the Pereda Gardens, consisting of four pools and a pond, entitled Desde lo subterráneo (From the Underground).

The sculptural intervention features five structures in grey stone enclosing overlapping iron pieces forming hollow spaces. They evoke the subterranean, the things that exist beneath the surface. Phreatic zones, underground areas saturated with water, pockets of water filled with foliage and molluscs, life speaking of the primordial ocean that gave origin to all forms of life on Earth.

Cristina Iglesias's permanent hanging sculpture is now on view at the Norman Foster Foundation.

The sculpture is constructed by several suspended screens that form a shadowed space between the old building and the new pavilion created by Sir Norman Foster. The screens are thread in carbon fiber following an excerpt of the novel “Paradise Fountains” by science fiction author, Sir Arthur C. Clarke, which talks about the ionosphere.
