This is a complex of museums (I think mainly ethnography) that was under restauration when I visited. It looks quite promising.
The Güpgüpoğlu Konağı (mansion) & Etnografya Müzesi consists of several buildings. The oldest dates back to the 15th century; afterwards changes and addings occurred up to the 18th century. The ‘Haremlik’ (private rooms) was turned into a ‘Müze – Ev’ (House Museum), with restored interiors and mannequins wearing historical dresses and illustrating 18th century daily life as well as festive occasions. The ‘Selamlık’ (reception rooms) and service area are organised as an Etnographic Museum, including old Seljuk and Ottoman artifacts. On the yard too, some old Islamic stone work is on display.
On the right side of the picture, in the background: The oldest part, dating from the 15th century. Its style is related to Syrian/Arabic and even Egyptian/Memluk architecture. Apart from the Mamluk involvement in Anatolian politics during those days, the Armenians could be a second component in this process: they were an important minority in the Kayseri region and – at the same time – Armenian builders and architects were the main (hired) force in the Mamluks’s military building projects in Egypt.
