During the time of our visit, restoration of La Pedrera (Casa Mila’s) façade was on-going, hence I can’t claim to have seen the building in its entirety. However, I came here for the chimneys which reminded me of the "Lord of the Rings" or Dr. Fate’s helmet from DC Comics. Anyway, this unique space is perhaps one of the best rooftops in the world.
Climb. There is a hidden stairway off the patio which servants used in the old days, so if the queue on the lift to the rooftop is quite long, ask an attendant to direct you to it. Be sure to be fit though as the climb is 8 floors up.
