This magnificently preserved Roman triumphal arch was constructed in 130 AD to commemorate Emperor Hadrian's visit to the city he called Attaleia, its three arched openings and ornate marble columns creating the most impressive entrance to Kaleiçi's old town. The gate's remarkable condition—one of the best-preserved Roman arches anywhere—owes to centuries of burial within the city walls before excavation revealed its grandeur. The Corinthian columns, carved friezes, and the towers flanking the arch demonstrate the importance of Antalya as a Roman provincial capital and trading port.

Antalya's atmospheric historic quarter fills the area within the ancient walls, its narrow cobblestone lanes winding past Ottoman-era wooden houses, Byzantine churches converted to mosques, and the boutique hotels and restaurants that have transformed this neighborhood into the city's most desirable destination. The old town's layers of history—Roman foundations supporting Ottoman mansions that now house modern cafes—create an archaeological experience simply by walking its streets. The residential lanes, hidden gardens, and the dramatic cliff-edge restaurants overlooking the harbor reveal the authentic character that development outside the walls cannot replicate.

The ancient harbor that has served Antalya for over 2,000 years curves beneath the cliff-top old town, its picturesque collection of wooden gulets, restaurants, and tour boats creating the scene that defines Antalya's maritime character. The harbor's protected position within the natural bay made it an essential port for civilizations from the Hellenistic period through the Ottoman era, and today it serves as departure point for boat trips along the coast and to nearby beaches. The surrounding cafes, the boat-building workshops, and the views up to Kaleiçi's cascading rooftops create one of Turkey's most romantic waterfront settings.

The symbol of Antalya rises 38 meters above the old town, its distinctive fluted red brick design dating from the 13th-century Seljuk sultan Alaeddin Keykubad who converted the Byzantine church below into a mosque. The minaret's unique ribbed surface and turquoise tile decorations represent the architectural innovations of the Seljuk Turks who transformed Anatolia and left monuments throughout the region. The surrounding complex includes the mosque, a former dervish lodge now housing the Ethnographic Museum, and the shaded tea gardens where locals gather.

One of Turkey's finest museums displays treasures from the ancient cities of the region—Perge, Aspendos, Side, and Termessos—in galleries that trace thousands of years of Anatolian civilization. The Hall of the Gods houses an extraordinary collection of Roman statuary including figures of Aphrodite, Apollo, and the emperors that once adorned temples and public spaces throughout the region. The prehistoric, Byzantine, and Ottoman collections complete a survey of the cultures that have flourished on Turkey's southern coast.

The best-preserved Roman theater in the world stands 50 kilometers east of Antalya, its 15,000-seat auditorium and elaborate stage building remaining so intact that it still hosts opera and ballet performances during the annual Aspendos Festival. The theater's remarkable acoustics—a whisper on stage can be heard in the highest seats—demonstrate Roman engineering at its finest, while the massive stage wall with its two tiers of columns creates the backdrop that original productions would have used. The surrounding ruins of the ancient city, including the spectacular Roman aqueduct, extend the archaeological experience.

This impressive ancient city 18 kilometers northeast of Antalya preserves one of Anatolia's most complete Greco-Roman urban landscapes, its colonnaded streets, massive stadium, and Roman baths revealing the prosperity of the region under Greek and Roman rule. The city's legendary foundation by Greek heroes fleeing Troy and its role in the journeys of Saint Paul add mythological and biblical significance to the archaeological interest. The stadium, one of the best-preserved in Turkey, and the elaborate city gate with its twin towers provide highlights among the extensive ruins.

The Düden River creates two spectacular waterfalls near Antalya—the Upper Düden Falls surrounded by parkland perfect for picnics, and the Lower Düden Falls where the river cascades directly into the Mediterranean in a dramatic 40-meter plunge. The lower falls can be viewed from boats departing the old harbor, providing a unique perspective on this natural wonder where freshwater meets the sea. The upper falls' surrounding park, with paths behind the waterfall itself, offers a refreshing escape from summer heat.

This mountain-top city 30 kilometers northwest of Antalya occupies one of the most dramatic archaeological sites in Turkey, its ruins scattered across a 1,000-meter peak that even Alexander the Great failed to conquer. The theater commanding views across the mountains, the rock-cut tombs, and the temples that served this fiercely independent city create an experience unlike the coastal sites—wild, atmospheric, and largely unexcavated. The site's location within Güllük Mountain National Park combines archaeology with hiking through forests where wild goats and endemic plants thrive.

Antalya's main public beach stretches seven kilometers along the coast west of the city center, its pebble shore backed by the Beydağları mountains that create one of Turkey's most dramatic beach backdrops. The Beach Park promenade provides cafes, restaurants, and facilities while the turquoise waters offer swimming and water sports in the clean Mediterranean. The Antalya Aquarium, one of the world's largest, and the surrounding park areas extend the beach experience beyond simple sunbathing.
