The eye is drawn to the four minarets of the Three-Balconied Mosque, built in the middle of the 15C during the reign of Murat II. None of these resemble each other, although the most remarkable, which is also the tallest, the last to be built, and the one that has lent its name to the building, supports three galleries (or balconies). This mosque marks a turning-point in architectural style, as it was the first time that an architect innovated in such a way, placing the central cupola above a rectangular floor plan in order to demarcate a vast interior space. The experiment worked as, despite the somewhat heavy pillars, the prayer hall is particularly elegant in appearance.
