East of the National Museum, and just over a kilometer west of the Old City lies the Tekkiye mosque complex. The mosque itself is the finest Ottoman monument in the city. It was built at the order of Suleiman the Magnificent, was planned by the Architect Sinan and was built mostly by Christian masons and architects who had converted to Islam.

The buildings that surround the mosque's courtyard were also built and planned by Sinan. They were built originally as accommodation for the Dervishes, who are known for their religious chants and whirling. It was used later as a khan to house pilgrims who were on their way to Mecca. On the east side is a Koranic School called the Selimiye Madrasa, which was built between 1566 and 1574. The prayer room of the Madrasa is still used as a school to teach Koran. The buildings round the school are currently being used by craftsmen, who sell  products such as glass, copper, jewelry, inlaid boxes and carpets.

East of the Tekkiye complex lies the Military Museum, which houses old weaponry and combat tools. This weaponry ranges from 13th century weapons used against the Crusaders and Mongols to modern Russian weaponry.
