Roof of La Pedrera

The Casa Milà, popularly known as La Pedrera, is one of the buildings where Gaudí developed his personal, unclassifiable style. The building involved a series of constructive novelties, such as the curtain wall façade, conceived as if it were a sculpture and the pedestal of the image of the Virgin that was to crown the building.
The roof of the building is particularly remarkable, with its vents and chimneys laid out according to the principles of ruled surface geometry. As in all of Gaudí’s buildings, the roof is integrated into the façade and walls. It also collects rainwater and channels it for later use.
