Praia do Cassino

Praia do Cassino is the longest sea beach in the world and is located in the southernmost of the Brazilian coast, on the South Atlantic Ocean, in the state of Rio Grande do Sul. It is the longest uninterrupted sandy seashore in the world, with various sources measuring it from 212 kilometres to 254 kilometres, stretching from the Molhes at the entrance of the Rio Grande seaport in the north to the mouth of the Chuí Stream, on the border with Uruguay, in the south.

On Nov. 12, 1966, during a total solar eclipse visible in Praia do Cassino, NASA scientists and U.S. Army have launched several rockets to study upper atmosphere.
