Antonio Gaudí was a Spanish architect from the late 19th and early 20th centuries known for his unique organic architectural designs. He began his career designing in a gothic style but developed his own sculptural style influenced by nature. Gaudí's most famous work was the unfinished La Sagrada Familia cathedral in Barcelona, which he devoted much of his life and career to designing. The cathedral was intended to have 18 towers and feature hyperboloid structures inspired by nature. Late in his life, Gaudí suffered personal losses and Barcelona faced economic difficulties, slowing progress on the cathedral. He died in 1926 after being struck by a tram in Barcelona.
