The Wallachian ruler, Neagoe Basarab, was a spiritual child of Saint Nifon. In 1520, he funded the construction of the Monastery's impressive defensive tower and the arched aqueduct that replaced the previous wooden one. He also donated an important relic to the Monastery: the cranium of St John the Baptist (which was unfortunately later stolen), in a golden case, and a gold-plated box in the shape of a church, where the relics of Saint Nifon were placed.
