Erzurum is a real historical treasure, with its centuries-old mosques, forts, towers and large tombs with dome shaped or conical roofs. The Twin Minaret Madrasah, the symbol of the city, dates back to the Seljuk period. The architrave of its portal, with its stone carvings, is among the most beautiful examples of Seljuk art. The minarets on either side of the portal are 26 meters high and decorated with turquoise colored glazed tiles. Üç Kümbetler, a group of three tombs, is one of the monumental structures in Erzurum. The largest of these tombs is the tomb of Emir Saltuk, the founder of the Saltuk State. The tomb is constructed according to an octagonal plan. The most interesting mosques in the city are the Grand Mosque, built in the 12th century, and Lala Mustafa Pasha Mosque built in the 16th century. The Rüstem Pasha Caravanserai was built by Rüstem Pasha, the Grand Vizier of Sultan Süleyman the Magnificent. The caravanserai, which displays the characteristics of 16th century Ottoman architecture, is still in use as a market place. In it are the workshops processing the famous “Oltu” stone.
