On the web I found, translated "It was purchased from an Armenian family by the writer Esma Ocak, who was raised in Diyarbakır, and was repaired and turned into a museum. The mansion, which is one of the most beautiful examples of traditional Diyarbakır houses, is positioned in a "U" shape around a square courtyard. The east and south wings of the house consist of the basement and ground floor, and the west wing consists of the ground and first floor."
I have the feeling the museum has been turned into a restaurant, on my pictures the many tables with eating tourists are (still) lacking.
