Porto Alegre, the capital city of the Brazilian state of Rio Grande do Sul is being called ‘the most beautiful street in the world’. Why? Take a look at these photos and see for yourself. Each side of the street is lined with trees, with some as tall as the 7th floors in adjacent buildings. What makes it even more beautiful is the fact that to either side of this forest of trees lies building after building, so it’s refreshing to see towering trees preserved in the city. People are even so fond of the trees here that ‘groups are working to preserve this street’s natural beauty’.
