Saint Fructus was an eighth-century anchorite from Segovia, Spain. Born into a noble family, he and his two siblings, Valentine and Engratia, chose a life of solitude following the death of their parents. They donated their inherited wealth to the poor before retreating to the rocky terrain near Sepúlveda. There, they lived as hermits in separate caves to maintain complete isolation from society during a period of significant regional instability.
