Rio Grande is located in the south of Brazil, near the border with Argentina and within the state of Rio Grande do Sul. Rio Grande was the state capital from 1835 to 1845. It is the most important port city in the state and has one of the most important maritime ports in Brazil. According to WIkipedia, the city of Rio Grande was founded in 1737 by Brigadier General José da Silva Pais and his men to defend Portugal's territory in America. I have some photos taken there so you can see how this city is. The photos were taken in 2018.
