Erzurum Castle , locally known as Erzurum Kalesi , lies on top of the hill in the center of the city of the same name , in the province of Erzurum in Turkey . The first fortification at this site was probably built in Urartian times . Throughout history Erzurum changed hands frequently between the Assyrians , the Sassanids , Persians , Arabs , Romans and Byzantines . The present castle however was built in 415 AD under the Byzantine Emperor Theodosius II . In the 11th century Erzurum Castle came into the possession of the Saltukids . Under the Saltukid Bey Muzaffer Gazi ( 1124 - 1132 ), the Tepsi Minaret was built in the south west corner of the inner castle . Somewhat later , in the mid - 12th century , the Saltukids also built the still remaining Mescid , which is a kind of chapel , in the inner castle . Erzurum Castle was seriously devastated in almost every period of conquest but was rebuilt and restored every time by the new rulers . One of the last rebuilding phases took place in the 16th century by the Ottoman Sultan Suleiman the Magnificent . After Erzurum Castle lost its military function it was used for storage . In the mid - 19th century stones of some sections were taken down to be used in the repair of some of the 18th century bastions in the hills around the city . Also in the 19th century , the upper part of the Tepsi Minaret collapsed . It was rebuilt in its present appearance with a clock . Hence its present name Saat Kulesi , meaning Hour Tower .
