Architect Frank O. Gehry designed the Hotel Marqués de Riscal in collaboration with architect Yves Collet. Situated in Elciego, Spain, the Hotel Marqués de Riscal is a luxury collection hotel and spa in the heart of the vineyards of the Rioja Alavesa wine region.

30,000 square feet of titanium were utilized by Gehry to form the immense ribbon-like facade which is an attraction in itself. Inside, a stunning glass passage going to the spa was designed by Collet.
