Spain’s renowned Rioja wine region is dotted with both traditional wineries and others that push the boundaries of modern design. Surprisingly, Rioja’s largest winery is perhaps its most architecturally significant.

Designed by architect Ignacio Quemada Sáenz-Badillos in 2001, Campo Viejo appears from the distance as two small, modern buildings sandwiched between rows of vines on one side, and a dramatic drop on the other. Quemada sought to build something that wouldn’t “ruin” the natural beauty of its surroundings. His solution? Bury the 480,000-plus-square-foot structure underground.

Adjacent to the main fermentation tank room is a far smaller “experimental winery.” One of the first commercial products to emerge from here is the winery’s Tempranillo Blanco-Virua blend. Tempranillo Blanco was discovered in 1988.
