Ioannis Koukouzelis or John Kukuzelis (Durrës, Albania 1280 – Athos 1360) was a Byzantine medieval Orthodox Christian composer, singer and reformer of Orthodox Church music. Because of his singing abilities, he was called “Angel-voiced”. He was recognized as a saint by the Orthodox Church after his death. He spent his last years on Mount Athos, where he lived in the cell of the Archangels of the Great Lavra.
This is the cell where John Kukuzelis lived. In the background the tower of Lavra monastery. This is one of the earliest photographs from the cell taken in 1853.

Athos - Agios Oros 
My dear friends, the first photo is not Archangelos. It’s Agii Paraskevi’s chapel. The second photo shows the Archangelos!
Thanks Jemmo. I will correct this. Fotos 3 and 4 are right, I hope? Please let me know.
No! This is Agii Paraskevi!
Better?
Yes, but map by Peter Howorth is not correct! Anargiri and Arhangeli have switched places.
