The coin of the Mint of Poland is a tribute to the Spanish visionary. The reverse is inspired by the colourful patterns and biomorphic shapes that are Gaudí's trademark. Antoni Gaudí was a Catalan Art Nouveau architect and engineer, famous for his exceptional designs. A turning point in Gaudí's life turned out to be a meeting with the Barcelona industrialist Eusebi Güell, with whom the architect struck up a friendship. Eusebi Güell appreciated Gaudí's art and financed the execution of a great many of his projects until 1918, when he died. Gaudí created a number of buildings for him, among them a hunting pavilion and a church. During this time he also designed for other Catalan entrepreneurs, as well as for the Church (the bishop's palace in Astorga and buildings for the Order of St Teresa). He completed a total of about 20 major projects, mostly in and around Barcelona. In 1883 Gaudí took over the commission to build the penitential temple Sagrada Familia, but he did not really work on it until 1914. What is more interesting is that he only had to finish the finished project by Francisco Villar. After 1914 Gaudí devoted himself completely to the temple. He even lived in the area of the building and after his death he was, according to his wishes, buried in it. Gaudí's style was very sculptural and Art Nouveau. He sometimes referred to the fluidity of the underwater world. Today he is considered a precursor of biomorphic architecture.
