This is an ancient city located at the southern portion of the Debub region of Eritrea. Also known as Kohaitto, these ruins were first excavated in 1868. It is a historic ruin that covers over 15km. The original town was situated 2500 metres above sea level at the edge of the Great Rift Valley. A short walk from Qohaito takes you to the edge of a vast canyon that plummets dramatically.
