This stunning aquarium looks like it’s been swallowed by the sea

Tatiana Bilbao Estudio’s concrete aquarium blurs the line between ocean, land, and building.

Should the oceans rise up and envelop the new Sea of Cortez Research Center in the Mexican city of Mazatlán, its true design intent will have been realized. The building is a bold and visually stunning concrete bunker that houses a unique new aquarium. Situated on the coast of the Mexican mainland, across the Sea of Cortez from the southern tip of the Baja California peninsula, it was designed by the Mexico City-based architecture firm Tatiana Bilbao Estudio.
