Metropol Parasol – Seville, Spain

If you want to know what Alice felt like in Wonderland, head to Seville, where a trippy new pavilion has sprung up in the Plaza de la Encarnacíon. Undulating blonde timber structures with a honeycomb roof make up the world’s largest wooden building, known by locals as “Setas de la Encarnación,” or the Mushrooms of Incarnation. It’s home to an archaeological museum, a farmers’ market, and an elevated plaza with bars and restaurants.
