Casa Batlló

• Dragon-back rooftop with mosaic chimneys and a curved tiled ridge, the part kids remember most
• Tablet smartguide included with entry, overlaying animations on each room as you move through
• Timed-entry tickets booked online for a set slot, so the line stays short if you arrive on time

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 central light well to a noble floor of wavy stained-glass windows and a mushroom fireplace, then up to the rooftop terrace, whose scaled, dragon-back ridge and mosaic chimneys are the high point. A tablet guide animates each room.
