Ocoa is a valley and locality located in commune of Hijuelas in the interior of Valparaíso Region, Chile. Historically Ocoa was the site of a large landholding owned by the Jesuits. There the Jesuits grep hemp. It was confiscated during the Suppression of the Society of Jesus in 1767. Folklore says Jesuits buried their valuables.[2] By some accounts the buried treasure was once found but nothing was extracted since the vault proved resistant to dynamite.[2] Another saying tells that those who seek to recover the treasure become cursed.[2]
