About this source

What it is

Casa Milà, nicknamed La Pedrera ('the stone quarry'), is a Modernista apartment building in Barcelona designed by Antoni Gaudí and built between 1906 and 1912. It was commissioned by Pere Milà and his wife Roser Segimón, with wrought-iron balcony work by Josep Maria Jujol. It was Gaudí's last private residence project.

Why it matters

The building's undulating stone facade, twisting ironwork, and self-supporting structure were highly innovative and controversial when built, mocked in the press of the time. Gaudí had planned religious statues of the Virgin Mary and archangels on the building, reflecting his Catholic faith, but these were dropped after anticlerical unrest in the city. It became a UNESCO World Heritage Site in 1984.

Look closer

  • Why do you think people at the time found this building's shape so unsettling?
  • What does the removal of the religious statues tell us about the political tensions of the period?
  • How does the building's structure differ from a typical apartment block of its era?
