Charter of HilandarHilandar Ι.Μ.Χιλανδαρίου, Agio
Together with his son Saint Sava, Nemanja restored the Hilandar Monastery at Mount Athos from 1198 to 1199, and issued the "Charter of Hilandar". The Charter of Hilandar is the founding charter of the Hilandar monastery, the cradle of the Serbian Orthodox Church and main endowment of Stefan Nemanja and Saint Sava.
The monastery thus became the center of Serbian Orthodox monasticism at Athos. Shortly after his death, Serbian Orthodox Church canonized Stefan Nemanja, under the name Saint Simeon the Myrrh-streaming.
