The City of Buenos Aires was founded twice. The first foundation happened in 1536, when the Spanish colonizer Pedro de Mendoza established the first settlement. Named City of the Holy Spirit and Puerto de Santa María del Buen Ayre. The second and definitive foundation was made by Juan de Garay in 1580, who called the site Ciudad de Trinidad. During the second half of the nineteenth century, the port was the arrival point for the great migratory wave promoted by the Argentine State to populate the nation. Spanish, Italian, Syrian-Lebanese, Polish and Russian immigrants provided Buenos Aires with the cultural eclecticism that distinguishes it. Throughout the twentieth century, successive migrations (internal, of Latin America and Asia) completed the picture of Buenos Aires as a cosmopolitan city where people live in different cultures and religions.
