El Nido de Quetzalcóatl (The Nest of the Feathered Serpent) is an apartment complex in Naucalpan designed by Mexican architect Javier Senosiain. The building takes the form of a serpentine structure coiling around a central courtyard, its surface covered in a mosaic of ceramic tiles in blue, green, and yellow — evoking the scales of the Aztec feathered serpent deity. The organic, curving forms stand in complete contrast to the rectilinear apartment blocks surrounding it.
The complex is a residential building and not generally open to visitors, but the exterior — fully visible from the street — is worth the detour for anyone interested in architecture or folk art. The neighbouring Nautilus House (also by Senosiain, a private residence shaped like a seashell) makes a good companion piece. Together they represent a distinctly Mexican strand of architectural experimentation that draws on both pre-Columbian imagery and organic form.
