Casa Milà (La Pedrera)

Gaudí’s huge, curved apartment building was dubbed 
La Pedrera (The Stone Quarry) by locals when it was completed in 1912. There isn’t a straight line anywhere, including inside the apartments, of which one is open to visitors. All the Modernista furniture and fittings were created by the finest craftsmen of the era. The vaulted attic has a museum dedicated to Gaudí’s work. The highlight is  the undulating panoramic rooftop, guarded by chimneys covered in shimmering tiles. Check for special guided tours at night (8pm-midnight) and summer music events. Open daily 9am-8pm Mar-Oct; daily 9am-6.30pm daily Nov-Feb.
