Kaunos, an ancient city of Caria and later Lycia, was located a few kilometers west of present-day Dalyan in Turkey’s Muğla Province. Originally the Calbys River, now the Dalyan River, Caria and Lycium were naturally separated by this river. Originally an independent state, Kaunos later joined Caria and was finally subsumed into Lycii’s territory.

Thought to have originated in the tenth century BCE, Kaunos developed as a major harbor. But geological changes—especially the silting of the Dalyan Bay and the creation of İztuzu Beach from roughly 200 BCE forward—have caused the city to be situated roughly eight kilometers inland. Kaunos had two harbors: an inner port, now Sülüklü Göl (Lake of the Leeches), which stayed in use until the city’s fall; the southern port, which served the city until the Hellenistic period when siltation made it useless.

Kaunos was utterly abandoned after the Turkish conquest of Caria and a terrible malaria epidemic in the 15th century CE, leaving behind an archeological wealth of former splendor.

Scholars knew about Kaunos, but its exact site stayed mysterious until 1842 when English archaeologist Charles Fellows found its remnants. Later, Swedish archaeologist P. Roos defined the territory of the ancient state, which comprised large coastal areas running from Fethiye Bay in the north to the mountains between modern-day Muğla and Antalya.

Under Turkish archaeologist Prof. Baki Öğün, systematic excavations started in 1966 and are still under way now under Prof. Cengiz Işık. These digs have produced amazing new understanding of the urban design, infrastructure, and cultural scene of the city. Beyond Kaunos proper, investigations cover surrounding sites like a sanctuary honoring the goddess Leto near the Sultaniye Spa.

Kaunos was a distinct culture with a language all their own, different from yet connected to Carian. Though mostly undeciphered until recently, the Kaunian script has elements of Carian but features five unique characters. Regarding the linguistic uncertainty, Herodotus observed that it was not certain if Kaunos affected Carian or vice versa. But the finding of a bilingual Greek-Carian inscription offers vital new perspectives on Kaunian language translation and comprehension.

Culturally, Kaunos displayed considerable indigenous customs—especially in relation to its religious rituals. Baselius Kaunios, the patron god of the city, was revered with customs different from those of his Lycian and Carian counterparts. Elaborate rock-cut graves, unique to Kaunos, highlight even more its own burial customs.

Built on a sequence of terraces, Kaunos combined architectural genius with natural geography. Significant religious and civic buildings such the Baselius Kaunios Temple, the Apollon Sanctuary, and the Demeter Sacred Rocks stood in the upper city, sometimes known as the Acropolis. These sites capture the syncretism with Greek and Anatolian belief systems and religious variety of the city.

The lower city included palestra, theater, and a bath complex among other public and governmental facilities. Linking the Acropolis to Balıklar Mountain, a massive terrace created a natural second harbor basin reaching into the Mediterranean.

Given their disproportionate scale in relation to Kaunos’ population, the city walls imply that the governing authorities expected the city to be strategically important as a nautical and commercial center. Together with inscriptions about trade rules, these fortifications offer vital proof of Kaunos’ economic wealth in antiquity.

Thriving as a major port city, Kaunos helped trade between the Aegean Sea and the Eastern Mediterranean. Production of specialized items, marine trade, and agriculture drove the city’s economy. Kaunian exports were black mastic, pine resin, salt, and salted fish—all basic goods for shipbuilding and repair. The city also participated in the slave trade, therefore reinforcing its economic character.

Kaunos was rich, but foreign powers—including the Persian Empire—constantly threatened it. Along with Xanthos, it was one of the few Anatolian cities to oppose Persian rule, but at great financial pay-off to keep its semi-autonomous status.

From the 5th century BCE, Kaunos’ currency clearly shows its affluence and political independence. With initials “K” and “B” (Kbid), early Kaunian coins show a winged figure on the obverse and pyramidal monoliths on the reverse, therefore commemorating the city’s former name. Reflecting both artistic excellence and economic power, these coins are important in Anatolian numismatic history.

Along with architectural pieces suggestive of great Hellenistic and Roman influence, archeological discoveries include pottery and sculptures. Suggesting habitation far before the architectural maximum in the 4th century BCE, the neck of a Protogeometric amphora from the 9th century BCE is the oldest object found at Kaunos.

Kaunos’s maritime prominence nonetheless, its prosperity declined as the silting of its harbors made passage more difficult. The city had become far less economically important by late Roman times. The development of malaria in the 15th century CE marked the last blow, forcing its surviving people to flee the city entirely.

With traces of temples, fortifications, and rock-cut tombs providing priceless insights into the political and cultural dynamics of ancient Anatolia, today the remains of Kaunos serve as evidence of their previous grandeur.

Kaunos has historical and cultural value much beyond its physical boundaries. Being a city between several civilizations gives one a different viewpoint on the junction of Anatolian, Greek, and Persian influences. Its strategic maritime importance, unique language legacy, and amazing archeological finds set it out as an unmatched location of antiquity.

Understanding ancient urban planning and sociopolitical institutions depends much on the city’s urban layout, rock-cut tombs, and early Anatolian architectural innovation. The well-preserved remnants of its trading infrastructure, including salt-pans and measuring platforms, highlight even more its economic value.

Kaunos ultimately reflects the resiliency and inventiveness of an ancient culture that survived environmental changes and geopolitical turmoil. Its remains guarantee their position as a priceless historical and cultural monument since they still provide great insights into the past.

History of Kaunos Ancient City

Mythological Origins and Early Settlement

Ancient legend holds that Kaunos was established by grandson of the sun god Apollo, King Kaunos, the son of Carian King Miletus and Kyane. His narrative is linked with the one of his twin sister Byblis, who held an illicit love for her brother. Unable to match her emotions, Kaunos left with his people to create a new city, leaving Byblis hopeless. Depressed, she started a frantic hunt for her brother before finally trying to take her life. Legend has her constant tears creating the Calbys River, a monument to her loss.

With the oldest known artifact—the neck of a Protogeometric amphora—archaeological evidence points to Kaunos as being inhabited as early as the ninth century BCE. Further discoveries point to a prosperous settlement by the sixth century BCE, including bits of Attic ceramics and a monument found at the western gate. But no architectural work has been absolutely dated to before the 4th century BCE.

First Persian Rule

Greek historian Herodotus, who tracked the Persian invasion of 546 BCE, first notes Kaunos in historical archives. Faced with opposition from the Lycians, Carians, and Kaunians, the Persian general Harpagus launched an attack against them finally subjugating them. Though Kaunian assertions of Cretan heritage, Herodotus hypothesised that they were native to the area and noted their unique customs, especially their communal social drinking practices, which distinguished them from their Carian and Lycian counterparts.

Kaunos took part actively in the Ionian Revolt (499–494 BCE), a broad uprising against Persian rule. Important Carian inscriptions, including a bilingual inscription in Greek and Carian, discovered in 1996 and significantly helped the Carian script to be deciphered, therefore underscoring the historical relevance of the city.

Greek Influences and the Delian League

Persian armies left the western Anatolian shore progressively after Xerxes I was defeated in the Second Persian War. Later Kaunos became a member of the Delian League, an association of Greek city-states run under Athens. The city’s tribute was first established at a meager one talent of silver, but by 425 BCE this figure had doubled, showing Kaunos’s rising commercial activity. Agricultural output and exports—including salt, salted fish, pine resin, black mastic (used in shipbuilding), and dried figs— drove economic development. Reflecting growing Hellenistic influence, the city changed its old name, Kbid, to Kaunos in the fifth and fourth centuries BCE. It is thought that the myth of the city’s founding developed around this time, therefore supporting its inclusion into the Greek cultural scene.

Second Persian Rule and Hellenistic Transition

Once Persian sovereignty over the area was reestablished with the Peace of Antalcidas in 387 BCE, Kaunos’s political destiny changed once more. The city changed significantly under the Carian satrap Mausolos (377–353 BCE). Terracing helped to extend and reorganize the urban scene, and great defenses surrounded a more extensive settlement area. Greek architectural features, such as an agora and temples honoring Hellenic gods, become increasingly noticeable, so highlighting the city’s changing cultural character.

Kaunos was included into the Macedonian Empire, therefore marking the end of Persian rule when Alexander the Great arrived in 334 BCE. After Alexander’s death, the city’s strategic location made it a sought-after prize among his successors, which set off a sequence of power battles among the Antigonids, Ptolemies, and Seleucids.

Roman Domination and Urban Development

Rome grew in impact into the Hellenistic kingdoms when they fell. Part of the Rhodian Peraia, the Roman Senate assigned Kaunos to Rhodes in 189 BCE. But this configuration caused opposition, which resulted in a revolt against Rhodian rule in 167 BCE. Rome then withdrew Rhodes’ administrative authority, and by 129 BCE Kaunos was included into the Roman province of Asia, running alongside Lycium.

The city got caught in the Mithridatic Wars in 88 BCE when Pontus’ King Mithridates VI invaded Rome. Supporting him, the Kaunians destroyed the Roman population of their city. But Rome exacted punishment by restoring Rhodian control after the peace settlement of 85 BCE. Kaunos thrived as a Roman seaport in spite of political instability because of infrastructural improvements like the enlargement of its amphitheater, the building of Roman baths and a palaestra, and the refurbishment of the agora fountain.

Byzantine Era and Christianization

Among the early cities to welcome the new faith as Christianity grew, Kaunos was The city’s moniker changed to Caunos-Hegia as the Roman Empire formally embraced Christianity. Mosaics and a domed basilica among other Byzantine architectural features point to its ongoing religious and cultural importance during this age.

Decline and Abandonment

As Muslim Arab invaders and seaborne pirates relentlessly attacked the city, Kaunos’s fortunes started to decline in the 7th century CE. Further upsetting the area, the 13th century brought incursions from Turkish tribes. The city was strengthened in response with medieval-style walls to provide brief protection from outside dangers. But the city’s economy was badly disrupted by the fall in marine traffic and the silting of the harbor, which led to significant migration.

By the fifteenth century, Kaunos was hardly known. After the Ottoman Turks had consolidated their rule over Caria, a terrible malaria outbreak delivered the last blow and caused the city to be abandoned. Natural events, including earthquakes, buried its remains even more under layers of dirt and plants.

Kaunos was forgotten until 1840 when Royal Navy surveyor Richard Hoskyn came upon an etched law tablet indicating the municipal council and population. His latter work in 1842 sparked academic curiosity and helped to bring once-thriving ancient metropolis back into historical memory.

Main Archaeological Sites of Kaunos Ancient City

The Site of Kaunos

Ancient city of great historical value, Kaunos is also a refuge for natural wonders. Tucked within the Köyceğiz-Dalyan Special Environmental Protection Area, this location remarkably combines history with landscape. Its proximity to Dalyan on the western side of the old Kalbis River offers panoramic views of the surroundings, including the Dalyan River, İztuzu Beach, and lush wetlands bursting with life. Featuring a variety of buildings that convey stories of its multifarious history, the ruins of Kaunos are an evocative monument to the creativity of their ancient residents.

The Acropolis and Heraklion

Rising on a 152-meter-high rock, the Acropolis, sometimes known as Persikon, watches over the historic city. Its Byzantine defenses provide a window into a military might and urban design age gone by. Known in ancient times as Imbros, the Acropolis commands impressive views of the surrounding terrain from its base at Mount Tarbelos (present-day Mount Ölemez).

Heraklion, a lesser fortification originally projecting into the sea until the 5th century BCE, stands next to the Acropolis. In its heyday, this 50-meter-high cape—which had two ports—was a major marine base. From these heights one can see the busy activity of ancient Kaunos, the glittering estuary, and the peace of İztuzu Beach below.

The Theater

Tucked down on the Acropolis’ hill, the architectural gem known as Kaunos combines Roman and Hellenistic elements. This well-preserved construction, with a 75-meter diameter and an inclination of 27 degrees, could hold 5,000 viewers, therefore serving as a focal point of social and cultural life. The theater still organizes events sometimes that resonate with the echoes of old applause and drama.

The Palaestra and Roman Baths

Once used for athletic training, the palaestra is a remarkable site erected over what most likely was a place of worship. Beside it, the Roman baths indicate the grandeur of Roman architecture and its focus on public life. Huge in scope, these baths highlighted the might of the Roman Empire and delighted the Kaunians with their grandeur.

These baths were taken down in the Byzantine era, and components including the frigidarium were used for a church. Dating from 150 BCE, the wind-measuring station highlights even more Kaunos’s sophisticated urban design. Although seismic activity caused this platform to collapse, it is thought to have guided the placement of the city’s streets so guaranteeing ideal airflow as detailed by Roman architect Vitruvius.

A unique survivor from the 5th century CE, the domed Byzantine basilica on the palaestra terrace Built from recycled materials, the inner walls of this basilica were painted in frescoes; surrounding mosaics suggest its former glory.

The Port Agora, Stoa, and Nymphaeum

From the 4th century BCE until the late Roman era, the port agora—which lies close to Sülüklü Lake—was a hive of political, social, and commercial activity. Though most certainly melted during the Byzantine era, evidence of many bronze statues previously bordering the agora emphasizes their significance.

While the adjoining nymphaeum, originally Hellenistic in style, was later enlarged in the Roman era, to the north of the agora sits a covered stoa offering relief from the elements. Emperor Hadrian’s era inscriptions show changes in merchant tolls that reflect the financial difficulties caused by silting of Kaunos’s ports.

The Temples

Kaunos claims six Hellenistic and Roman-originating temples. Of them, the terrace temple from the third century BCE is particularly appealing architecturally. Nestled amid a circle of columns, this temple featured an obelisk, a sign of King Kaunos personally, as shown on old coins. These holy sites highlight the spiritual aspects of the people living in the city and their respect of their mythical and historical background.

Beyond the Archeological Site

The Rock Tombs of Dalyan

Among the most striking elements of the region are the rock tombs carved into the cliffs facing the Dalyan River. These tombs, which date back to the 4th–2nd centuries BCE, resemble the façades of Hellenistic temples with graceful Ionian columns, triangle pediments, and complex friezes. Their enormous weight and workmanship preserve the prominence of those buried within.

The Kaunos City Walls

Designed under Mausolos’ rule in the fourth century BCE, Kaunos’ city walls are a wonder of Hellenistic architecture. Their great scope points to ambitious ideas for the growth of the city as a marine and commercial powerhouse. Built from precisely formed rectangular pieces, these walls provide a picturesque walking route today by weaving along the slopes and cliffs.

The Niche Tombs at the Port of Çandır

Necropolises surround Kaunos, a relic of the old custom of burying the deceased distant from living quarters. Many niche tombs are cut into the Kızıltepe granite in the harbor of Çandır. Designed to hold urns carrying the ashes of the dead, these graves capture the simplicity and seriousness of past funeral customs.
