When the Guggenheim Museum Bilbao opened in northern Spain 25 years ago, architect Frank Gehry’s curvy titanium-clad building was itself as much a part of the attraction for many art lovers as the exhibits inside. 

As Spain opens the long-awaited Royal Collections Gallery in Madrid next week, its sleek new eight-story building, perched on an iconic hillside next to the Royal Palace, may also steal some of the attention from the Old Masters on display. Spanish architects Emilio Tuñon and Luis Mansilla won the 2017 American Architecture Prize and a dozen other awards for this design, built with white concrete, granite and oak and featuring hundreds of windows overlooking the leafy gardens below the Royal Palace and the expansive Casa de Campo park beyond.
