The best way to experience the Antalya region is by exploring Kaleiçi, the city’s charming old town. Its most famous historical landmark, Hadrian’s Gate, was built by the Romans and features three grand arches marking the entrance to this fascinating district. While Kaleiçi is predominantly shaped by the Ottoman era, its surrounding walls date back to Roman times. Another notable site is the Korkut Mosque, originally a 2nd-century Roman temple that was later transformed into a Byzantine church, a Seljuk mosque, a Crusader church, and finally an Ottoman mosque. Overlooking Kaleiçi’s picturesque harbor, Hıdırlık Tower—an ancient fortification—stands proudly along the city walls, offering visitors a glimpse into Antalya’s rich past.
