In the early 20th century, many Europeans (particularly Spaniards and Italians but also thousands from Central Europe) immigrated to the city. In 1908, 30% of the city's population of 300,000 was foreign-born. In that decade the city expanded quickly: new neighbourhoods were created and many separate settlements were annexed to the city, among which were the Villa del Cerro, Pocitos, the Prado and Villa Colon. The Rodo Park and the Estadio Gran Parque Central were also established, which served as poles of urban development.
