The Short List, 3 of 12: Casa Batlló




Antoni Gaudí remodeled this Passeig de Gràcia townhouse between 1904 and 1906, and almost nothing inside is straight. The route climbs from the blue-tiled light well to a floor of wavy stained-glass windows and a mushroom fireplace, then up to the rooftop, whose dragon-back ridge and mosaic chimneys are the high point. The tablet guide included with every ticket animates each room and comes in English.
