Antoni Gaudí (1852–1926) was the Catalan master of Modernisme whose organic, structurally daring architecture turned Barcelona into a pilgrimage city: the Sagrada Família (under construction since 1882), Casa Batlló, Casa Milà and Park Güell. Seven of his works are UNESCO World Heritage Sites — more than any other single architect. Here are the 15 projects that explain why.

Deemed a creative genius and a pioneer of the Art Nouveau architecture style and Catalan modernism, Antoni Gaudi is known for his distinctive style inspired by nature. Seven of his projects in Barcelona have been granted world heritage status by UNESCO, acknowledging his contribution to 20th-century modernism. His study of nature led to the usage of various geometric forms in numerous projects carried out by him. His style surpassed the influences of neo-gothic and oriental architecture, which is evident in his early works and forayed into an organic style that is unique to his design ideology. Here are 15 pioneering and groundbreaking projects by Gaudi- The architect of Barcelona. In this article, we explore Antoni Gaudi’s architecture projects that stand out.

Frequently Asked Questions About Antoni Gaudí
Who was Antoni Gaudí?
Antoni Gaudí (25 June 1852, Reus – 10 June 1926, Barcelona) was the defining architect of Catalan Modernisme. Deeply religious and obsessed with the geometry of nature, he spent his final decades on the Sagrada Família and died after being struck by a tram, mourned as “God’s architect”.
What is Gaudí’s most famous work?
The Sagrada Família in Barcelona, which he directed from 1883 until his death. Consecrated as a basilica in 2010, it remains under construction — its central Tower of Jesus Christ has been slated for completion in 2026, the centenary of Gaudí’s death.
How many Gaudí buildings are UNESCO World Heritage Sites?
Seven properties are inscribed as the “Works of Antoni Gaudí”: Park Güell, Palau Güell, Casa Milà, Casa Vicens, Casa Batlló, the Nativity façade and crypt of the Sagrada Família, and the crypt at Colònia Güell.
What style did Gaudí work in?
Catalan Modernisme taken to an organic extreme: structures derived from nature’s own geometry — catenary arches, hyperboloid vaults, tree-like columns — finished with trencadís, his signature mosaic of broken ceramic tiles.
Why was the Sagrada Família never finished in Gaudí’s lifetime?
Gaudí knew the project would outlive him — “my client is not in a hurry,” he said of God — and at his death in 1926 only a fraction was built. Work has continued ever since from his models and drawings. See where he ranks among the 20 greatest architects in the world, and how the Sagrada Família compares with the other most famous buildings and their architects.
