Located in the city center of Antalya and hosting boutique hotels, historical artifacts, museums, specially designed stores, stylish cafes and restaurants, Kaleiçi is surrounded by horseshoe-shaped walls inside and out. It is known that the walls are the joint work of the Hellenistic, Roman, Byzantine, Seljuk and Ottoman periods. There are about 3000 houses with tiled roofs inside the walls. The architecture of Kaleiçi outside the walls bears the traces of Ottoman architecture. The characteristic structures of the houses not only give an idea about the architectural history of Antalya, but also reflect the lifestyle, traditions and customs of the region in the best way.

It is possible to enter Kaleiçi through Hadrian's Gate. This gate is one of the best preserved of the historical buildings in Antalya. The building, which is a Roman work, was built in 130 AD on behalf of the Roman Emperor Hadrian.
