La Pedrera is one of the most important architectural works of the city, formerly the Milà House, it is better known as La Pedrera (The Quarry).

The Quarry is divided in two spaces: Gaudí Space, a museum about the career of the architect and his innovative techniques and the second space showcases temporary exhibitions, with over 20 exhibitions of artists of the likes of Dalí, Dürer or Clavé.

This is one of the main Gaudí residential buildings and one of the most imaginative of all his designs. The outside of the building is an impressive mass of rolling stone, where wavy walls made of rough, chipped stone give the impression of ocean waves!

The doors and windows look like they are dug out of sand and wrought iron balconies, each of which is different from the others. Look up and you will see its spectacular roof where the chimneys have been dubbed the "witch scarers", and El Pis, one of the flats now open to the public, is decorated as it would have been when the building was first occupied.

The building was recognized by UNESCO as "World Heritage" in 1984.
