Casa Batlló Entry with Self-Audioguide Tour

Gaudí remodeled this existing building between 1904 and 1906, giving it an undulating stone facade, skeletal balcony railings and a roofline said to represent Saint George slaying the dragon, a design so distinctive it's locally nicknamed the House of Bones. The self-paced audioguide covers the interior's flowing, almost aquatic rooms, where straight lines are nearly absent by design. With a near-perfect aesthetic score, it stands as one of Barcelona's most striking Gaudí interiors to actually walk through, rather than just view from the street.
