Hotel Marqués de Riscal, C/Torrea, 1 Elciego, Basque Country, Spain

Here’s a weird building that you can actually sleep in. The Hotel Marqués de Riscal was designed by the award-winning architect Frank O. Gehry and consists of curved metal flourishes and other unusual architectural effects. The architecture contrasts with the historic 19th-century wine cellars in the hotel. The rooftop lounge offers guests panoramic views over the medieval village of Elciego and the surrounding vineyards.
