In Barcelona, go inside one of Antoni Gaudi’s most celebrated buildings, La Pedrera, at night for a 1.5-hour multimedia event. The experience, known as Gaud?’s Pedrera: The Origins, takes you on a colorful journey through the landmark, culminating in a rooftop show where neon lights and projections transform his spiraling rooftop chimneys into giant candy-colored clouds or a galaxy of stars. Top off the evening with sweeping views of Barcelona as it twinkles below you, and a glass of Cava.
