Gonçalo de Carvalho Avenue

　　Gonçalo de Carvalho Avenue is situated in Porto Alegre, Rio Grande do Sul, Brazil. This over 500-meter-long tree-lined boulevard is hailed as “the most beautiful street in the world” and has become the city’s most iconic landmark, recognized as an “environmental heritage” site of Porto Alegre.

　　The avenue is named after the Portuguese missionary Gonçalo de Carvalho. Along its nearly 500-meter sidewalk, more than 100 tipuana trees stand in a row, some reaching heights of up to seven stories—truly breathtaking. From a distance, these trees naturally form an arched green tunnel, lush and vibrant, offering a refreshing and pleasant sight. In spring and autumn, the foliage is rich and full of life; in the summer heat, their dense canopy provides cool shade. This verdant boulevard has become a natural oxygen bar for Porto Alegre, supplying the city with fresh air. Walking through this naturally formed green tunnel brings relaxation and promotes both mental and physical well-being.

　　Thanks to the existence and unique beauty of Gonçalo de Carvalho Avenue, in 2006, the then mayor of Porto Alegre signed a decree declaring this beautiful street part of Brazil’s historical, cultural, ecological, and environmental heritage.
