"The sand-colored façade of Casa Milà—built as apartments and now housing some offices—is subdued for Gaudí, but the twisted pillars on the roof are eye-catching, and partly why this building represents a structural breakthrough for the architect. The visitable space includes a majestic internal courtyard, roof, and Espai Gaudí, an attic showcasing models and plans of Gaudí’s buildings. Casa Milà also attracts a discerning, culture-seeking visitor: In summer, the roof hosts cava and concert nights with classical performers" - Gemma Askham
