1 Best Sight in The Black Sea Coast and Lake Van, Turkey

Built in 1385 by Artukid Sultan İsa, this medrese (Islamic school) sits up just above the rest of the city, and its crenulated dome forms a Mardin landmark. The compound includes a courtyard (now a tea garden), a mosque, and a tomb intended for the sultan. Head up to the upper terrace for one of the best views of the city.
