Rua Goncalo de Carvalho is a street located in Porto Alegre, the capital and largest city in the Brazilian state of Rio Grande do Sul. Planted 70 years ago by German employees in a former brewery site, one hundred tipuana trees stretch approximately 500 meters on either side. In 2005, some of the trees were almost cut down to make a room for a shopping mall. However, the street became internationally known as the “world’s most beautiful street” after a campaign for its preservation. Today, this beautiful green street is appointed as historical heritage.
