This is a complex of museums (I think mainly ethnography) that was under restauration when I visited. It looks quite promising. If I am not in error its heart is the Güpgüpoğlu Konağı, an 18th century mansion, home to Ahmet Mithat Güpgüpoğlu, poet, composer and officer of the government.

This is a detail of a small monument in the garden, see the first picture of this series.
