The maze-like Kaleiçi neighborhood was made for strolling. Perfectly restored whitewashed and red-roofed Ottoman mansions line the cobblestone streets, now home to a plethora of boutique hotels, souvenir shops, art galleries, and restaurants. Although it's more a place to simply breathe in the old-world ambience, there are also plenty of small tourist attractions for those who want to sightsee.
The main square (Kale Kapisi) has a fortress gate and stone-clad clock tower, while the 18th-century Tekeli Mehmet Pasa Mosque is worth a look just for its stunning interior tile work. Along Hesapçi Sokak, you'll find the graceful Kesik Minare (truncated minaret). Destroyed by fire in the 19th century, this is all that is left of a building that started its life as a Roman temple, was converted into a Byzantine church, and finally became a mosque.
