Though far advanced in years, Bishop Aidan established the Caithair Culdich-Chair of the Culdees, or Cele De-at the Patriarchal School of Constantinople. There he spent his last days as teacher and advisor to the emperor's court, and there the esteemed monk died in the winter of 949, full of grace and wisdom.
Saint Aidan's tomb can be found in the Chapel of the Holy Fathers, in the shadow of the Hagia Sophia. Additional grave markers have been erected in the grounds of each of the four churches begun by him in what is now Sweden, Denmark, and Norway. A small memorial stone can also be found at Kells, and another on the island of Iona, ancient Hy, where some of his bones were taken for burial so that the Celtic Church might ever rejoice in the memory of Aidan mac Cainnech.
