Kaleiçi is Antalya's old town, a district of narrow cobblestone streets that run between restored Ottoman houses and sections of Roman wall down to the Mediterranean. People still live and work here, so the quarter feels like a neighborhood rather than an open-air museum, with cafes, small hotels, and shops occupying many of the old buildings. The area holds UNESCO World Heritage status, and there is no admission charge: you can wander the streets for free at any hour. Landmarks sit within walking distance of each other, including Hadrian's Gate, built in 130 AD, the 13th-century Yivli Minare, the Kesik Minare, and the old harbor, which has been in use for about 2,000 years. Allow three or four hours to cover it on foot.

Antalya's old quarter has Roman, Byzantine, and Ottoman construction layered in the same streets. Hadrian's Gate, built in 130 AD, is still a working pedestrian entrance. The city has about 2,000 years of building history on display.

Visitors interested in Roman and Ottoman architecture will find plenty here. Photographers tend to come late in the afternoon, when the stone catches low light.

First-time visitors and solo travelers both manage easily here. The area is walkable, and staff at most sites are used to tourists.

Antalya Marina is a 5-minute walk away and has waterfront restaurants. The Archaeology Museum is about a 10-minute drive and holds finds from Perge and other nearby sites.

Nearby bazaars sell Turkish crafts and souvenirs. Tea houses in the side streets are a good place to rest between sights.
