The monastery complex of Sanahin is located in the north of Armenia within the province of Lori. The foundation of the monastery probably dates back to Saint Grigor The Illuminator who is said to have erected a cross there in the fourth century. A chapel was built on the site, exactly where the Church Of The Redeemer is located today. Construction of the monastery began in the tenth century. It comprises three churches, two vestibules, a college, library and bell tower.
