Colégio de São Bento is a Benedictine school for boys in Rio de Janeiro, Brazil with a history that dates back more than 150 years. It was founded in 1858 on the hills overlooking Rio de Janeiro's harbor and the Guanabara Bay, by the adjacent Benedictine monastery (Portuguese: Mosteiro de São Bento). Although the school is still run by the monastery, students who attend it may come from any denomination or religion.
