Águas de São Pedro–São Paulo 1941 chess tournament
The Águas de São Pedro International Tournament () was a chess tournament held from 2 to 26 July 1941 in Águas de São Pedro and São Paulo. The event, the first international chess tournament of Brazil, was organized by the São Paulo Chess Club and sponsored by Antonio and Octavio Moura Andrade, being the latter founder of Águas de São Pedro and owner of the "Grande Hotel".
San Pedro Springs
The springs were named by Father Isidro Félix de Espinosa, a Spanish missionary, in 1709; but some scholars believe Álvar Núñez Cabeza de Vaca may have camped at the springs in 1535. That would make the springs one of the oldest historical sites in North America and the second oldest park in America, behind only Boston Common.
In 1718 Governor Martín de Alarcón established a settlement he called Villa de Béxar near the headwaters of San Pedro Creek, but civilian settlement did not materialize. 
Also, in 1718, another Spanish missionary, Antonio de San Buenaventura y Olivares, built a mission nearby the fort at San Pedro Springs that he named San Antonio de Valero. This was the first permanent European settlement in San Antonio.
