Saint Catherine's Monastery at the foot of Mount Sinai built in the time of Justinian I, traditionally known as Justinian the Great and also Saint Justinian the Great in the Eastern Orthodox Church, was the Byzantine emperor from 527 to 565
Also built during this time was the Chapel to the Holy Trinity, which lies atop Mount Sinai
