Originally named Semanoglu Mansion, the structure was built by Akkoyunlus in the 15th century. It was given as a present to Ataturk with the name of Gazi Mansion by municipality, after being bought in 1935, after being used as shelter during the World War 1. It is on the west of the Dicle Bridge outside the Mardin Door.
The mansion has two floors and an iwan on each floor with places on both sides of the iwans. At the moment, personal belongings of Ataturk, documents, and photographs are exhibited. The mansion, used as museum, has a unique beautiful view with the view of Tigris River, Hevsel Gardens, Kirklar Mountains, and Ten Eyed Bridge. Hosting the guests with sightseeing and picnic areas, a peaceful air is dominant to the mansion.
