I hope to one day visit this complex, it seems to be very fine. Strolling through Istanbul names it "... one of the most elaborate and picturesque of the smaller classical complexes. It was built by Hüseyin Paşa while he was Grand Vezir (1697-1702).
In 2015 I met a man who was checking measurements in preparation for a restoration. He could not tell me when that would start, let alone when it would be finished. In the meantime it is closed.

It is close to the Church of St. Polyeuktos.
