Gaudí's "House of Bones" on Passeig de Gràcia is a 1904 to 1906 makeover of an older building, with a dragon on the roof and balconies shaped like masks. The façade is free to see from the street, and it makes far more sense with someone telling you what it means. The inside visit takes about an hour to an hour and a quarter. Our city bike tour stops in front of it.

The Barcelona Bike Tour rides up Passeig de Gràcia, Barcelona's grandest avenue, to Gaudí's houses. We stop at the spot with the best view of Casa Batlló and its neighbours, not just the nearest corner, and always leave time to take photos and look around on your own.
While you look, your guide tells the story of the place: what the dragon on the roof is doing there, why the balconies look like skulls, and the facts and anecdotes behind the most photographed block in the city.
We don't go inside: entry isn't part of the tour. Seeing it with a guide first is a good way to decide whether you want to, and to know what you're looking at when you do.
The curved roof, covered in scale-like tiles, is usually read as the back of a dragon, and the tower with its cross as the lance of Saint George, Barcelona's patron saint, who slays it. Gaudí never explained it himself, which is part of the fun.
Look at the lower floors: the columns look like bones and the balconies like masks or skulls. That is why people in Barcelona have long called it the "Casa dels Ossos", the House of Bones.
Casa Batlló stands on the same block as Puig i Cadafalch's Casa Amatller and Domènech i Montaner's Casa Lleó Morera, three star architects competing on one street. In Spanish "manzana" means both a city block and an apple, so the locals named it after the golden apple of discord from Greek myth.
Inside, the central light well is tiled in blues that get darker towards the top, and the windows grow larger towards the bottom. The result is that light is spread evenly from the roof to the ground floor.
The hexagonal paving stones on Passeig de Gràcia, with their sea creatures, are a Gaudí design too. Look down while you look up.
Ride first and go in later, and you will know what you are looking at.
