A king's real-estate project
Antalya exists because Attalus II of Pergamon wanted a naval base on the southern Anatolian coast and picked a rocky limestone plateau with a natural harbor tucked beneath it. Around 159 BC he founded a city there and, with the kind of modesty rulers of that era rarely bothered with, named it Attaleia — after himself. The choice of site was purely practical: the plateau gave ships shelter from the open Mediterranean while sitting high enough to defend, and the harbor below could take on water, cargo, and a fleet.
When the last Pergamene king died without an heir, he willed his entire kingdom to Rome, and Attaleia passed to the empire along with it. Rome expanded the harbor into a base for its Mediterranean fleet and trade routes, and in 130 CE the city commemorated a visit from the emperor Hadrian with a marble triple-arched gate — the same gate that still stands at the entrance to Kaleiçi today, the only one of the city's original Roman gates to survive intact.
Conquered by sea, held by land
The Byzantine centuries that followed were unsettled ones — Arab raiding fleets, Crusader traffic, and repeated changes of overlord kept the port contested. That ended in March 1207, when the Seljuk sultan Kaykhusraw I took the city by storm, giving the Anatolian Seljuk state something it had never had before: a working Mediterranean harbor. Seljuk rule reshaped the skyline more than any conqueror before it. Around 1230 Sultan Alaeddin Keykubad I raised the fluted brick minaret — the Yivli Minare — that still functions as the city's most recognized silhouette, built beside a mosque converted from an older Byzantine church.
After the Seljuk state fragmented, Attaleia became the capital of a small frontier principality, the Beylik of Teke, for roughly a century. The Ottomans absorbed it in 1391 under Bayezid I, and Ottoman rule — administered locally rather than remade from the center — is largely why Kaleiçi's tangle of wooden-balconied houses and narrow lanes survived into the twentieth century instead of being replaced.
From sleepy port to the Turkish Riviera
For most of the twentieth century Antalya remained a modest provincial port, disconnected from Turkey's interior by the Taurus Mountains at its back. That changed with the completion of the coastal highway network and Antalya Airport's growth into one of the busiest in the country, turning the province into what is now marketed worldwide as the Turkish Riviera. The transformation happened almost entirely outside the old city: package resorts spread along the beaches at Lara and Konyaaltı and west toward Kemer and Belek, while Kaleiçi itself — the walled core a visitor actually explores — was restored rather than redeveloped, its Ottoman houses converted into boutique hotels and its Roman and Seljuk monuments left standing exactly where each was built.
That's the odd contrast a five-day visit runs into: arrive through one of the world's busier resort airports, then spend the walk from Hadrian's Gate to Kesik Minare passing through nine centuries of continuous, overlapping construction on a single square kilometer of ground — before the later days head out to Roman ruin fields the old city itself has no room for.
