Casa Amatller is one of Barcelona’s most famous modernist buildings, alongside La Pedrera and its geographic and stylistic neighbour Casa Batllo.

It was constructed in 1898 by the architect Josep Puig i Cadafalch, a contemporary of Antoni Gaudi. The construction was ordered by the industrial chocolatier Antoni Amatller, whose vision was of a modernist, gothic, yet urban palace. Unlike Gaudi’s voluptuous shapes next-door, the facade of Casa Amatller is mostly made up of straight line and plane surfaces. The style is inspired by both the Catalan Gothic aesthetic and the pointing triangular shape of Flemish architecture.

The building was declared an artistic and historical monument in 1976.
