Print with black ink illustration of the Casa Milà's roof by David Rendo, winner of the first competition of Sketching: "Dibuixa La Pedrera".

Walk around the roof of La Pedrera is to come across several Gaudí sculptures conceived with great aesthetic quality and functionality: the stairwells -for access to the roof and some of the stone in marble or ceramic trencadís coverings-, the ventilation towers -which help to renew the air in the attics- and the chimneys -smoke outlets-, grouped together in ensembles. These sculptural-architectural elements let the imagination run wild beyond their functionality and aesthetics.
