Casa Milà, popularly known as La Pedrera, meaning the ‘The Quarry’, is a modernist building in Barcelona. It was the last civil work designed by Antoni Gaudí, built between the years 1906 and 1910.It was commissioned in 1906 by businessman Pere Milà i Camps and his wife Roser Segimon i Artells. At the time, it was controversial because of the undulating stone facade and twisting wrought iron balconies and windows designed by Josep Maria Jujol.The work of Gaudí on the rooftop of La Pedrera was a collective of his experience at Palau Güell, but with solutions that were clearly more innovative – this time creating shapes and volumes with more body, more prominence, and less polychromasia.The stepped roof of La Pedrera, called ‘the garden of warriors’ by the poet Pere Gimferrer because the chimneys appear to be protecting the skylights.In 1984 it was declared a World Heritage Site by UNESCO.
