This mosque from 1485 lies a bit hidden in a market region, I find it a bit better in architectural detail than the Ali Pasha mosque on the central square, though they are obviously related in style. It was built on order of Beyazit II, whose mosque in Amasya is among my all-time favorites. Stylistically very similar, unfortunately this one does not have the large “kulye” complex of medreses, hospital, soup kitchen and all that.
I did not check this one, but often the pillars like the blue one in the centre top half could rotate, if they didn't rotate that was an indication the building had suffered from an earthquake. An early seismograph. A similar contraption is often inside, at both sides of the imams prayer niche.
