A mosaic floor measuring roughly 1.6 metres across has emerged near a Hittite palace at Kültepe in central Turkey, where archaeologists have worked for 78 years without finding another example of this kind. Discovered during the 2026 excavation season, the flooring belongs to a Hellenistic archaeological context and was accompanied by four previously unidentified layers from the same broad period.

The Discovery
Turkey’s Ministry of Culture and Tourism announced the discovery following excavations east of Warşama Palace, an important structure at the archaeological site of Kültepe in Kayseri province. The find came during the second excavation season of a research project launched in 2025.
The project brings together Turkey’s General Directorate for Cultural Heritage and Museums, Ankara University and South Korea’s National Research Institute of Cultural Heritage. Its work examines the settlement’s long sequence of occupation, including periods that have received less attention than Kültepe’s earlier history.
During the 2026 season, archaeologists uncovered part of a building with a mosaic floor. The surviving section measures 163 centimetres from east to west and 165 centimetres from north to south. Fragments of flooring found around the structure suggest that the original mosaic may have covered a considerably larger area.
The discovery is notable because excavations at Kültepe have continued for decades, yet no comparable mosaic floor had previously been reported in the site’s 78-year excavation history. Researchers also identified four distinct Hellenistic layers in the area, creating new opportunities to investigate the settlement during a period that remains less well understood.
What Archaeologists Found
The principal discovery is the surviving portion of a mosaic floor within a structure east of Warşama Palace. Although the exposed section is relatively small, scattered flooring fragments indicate that archaeologists may have uncovered only part of a more extensive decorative surface.
The excavation also revealed four Hellenistic archaeological layers that had not previously been identified in this area. These layers are important because they may preserve evidence of successive phases of occupation, construction or activity. Their precise relationship to the mosaic and the building still requires further investigation.
Researchers also examined the floor’s construction. According to the reported findings, builders first levelled the ground before laying a foundation made from crushed stone and fine soil. They then placed small river pebbles over the prepared base. Ceramic fragments, lime and other materials were also incorporated into the flooring.
These details provide evidence of the preparation that went into constructing a durable decorated surface. However, the surviving mosaic section does not yet establish the building’s original function. Archaeologists have not confirmed whether it belonged to a private residence, a public building or another type of structure.
Historical Background
The mosaic dates to the Hellenistic period, conventionally placed between 323 and 30 BC. This era began after the death of Alexander the Great, when Greek language, artistic traditions and cultural practices spread across territories extending from the eastern Mediterranean into western Asia.
Kültepe’s importance, however, began many centuries earlier. Known in antiquity as Kültepe-Kaniş and associated with the ancient city of Kanesh, the settlement was inhabited from the third millennium BC through the Roman period. It served as a significant political and commercial centre in Anatolia before and during the development of the Hittite state.
The site includes an Upper City associated with royal and religious buildings, alongside a Lower City containing a karum—a commercial district where merchants lived and conducted business. Thousands of cuneiform tablets recovered from Kültepe document transactions, agreements and aspects of everyday life among Old Assyrian and Anatolian trading communities.
This earlier history has made the site especially important to scholars studying commerce and the development of Anatolian societies. The new mosaic directs attention towards a later phase, when communities continued to occupy and adapt the settlement long after its earlier political and commercial prominence.
Scientific Analysis
The mosaic’s archaeological context provides the basis for assigning it to the Hellenistic period. The four newly identified layers offer additional evidence that may help researchers establish a more detailed sequence for the site’s development.
The flooring’s construction is another focus of study. Its prepared foundation, river pebbles, ceramic fragments and lime illustrate the combination of materials used in its manufacture. Further examination may clarify how the floor was assembled and whether its construction can be compared with examples from other settlements in Anatolia.
The fragments surrounding the surviving section could also help archaeologists reconstruct the mosaic’s former extent. At present, the exposed measurements describe only the preserved portion, not the complete dimensions of the original floor.
Other mosaics have been discovered elsewhere in Turkey, including a large floor with Greek and Latin inscriptions at a Roman-era villa in Kayseri province in 2023. At Hadrianopolis, archaeologists have uncovered later mosaics featuring animals, fruit and Greek inscriptions. These comparisons provide broader context for the region’s use of decorated flooring, but they do not establish a direct connection between those sites and the Kültepe mosaic.
Why This Discovery Matters
The discovery broadens the archaeological picture of Kültepe beyond its better-known Bronze Age remains. The settlement’s earlier importance is well documented through its commercial records and architectural remains, but its Hellenistic occupation offers additional questions about how the site changed over time.
The four newly identified layers could help researchers distinguish different phases of activity and understand how buildings and spaces were used during this later period. The mosaic also provides evidence of decorative flooring and building practices in a part of the site where such a feature had not previously been recorded.
The find has attracted attention partly because it emerged near Warşama Palace, a landmark associated with Kültepe’s earlier history. That location makes the relationship between the settlement’s different periods especially interesting, although proximity alone does not prove continuity of use between the palace and the later building.
What might the mosaic tell us about life at Kültepe during the Hellenistic period: the activities carried out inside the building, the status of its occupants or the changing appearance of the settlement? Further excavation and analysis may help researchers test these possibilities.
The discovery also demonstrates the value of international archaeological collaboration. Turkish and South Korean institutions are working together to investigate the site’s stratigraphy and artefacts, potentially expanding understanding of a settlement occupied across several millennia.
What’s Next?
Researchers plan to study artefacts from the newly identified Hellenistic layers alongside the remains of the building and mosaic. Their goal is to develop a clearer chronology for the settlement and better understand how people used the area during this period.
Further excavation may reveal more of the floor and establish whether the surrounding fragments belong to the same decorative surface. Archaeologists will also need to clarify the building’s function and the relationship between the mosaic and the four archaeological layers.
The wider project will continue to investigate deeper deposits associated with the Kingdom of Kaniş and the Hittite period. This work may help place the new discovery within Kültepe’s longer sequence of occupation while documenting changes across different historical eras.
Conclusion
The Hellenistic mosaic discovered near Warşama Palace adds a new chapter to the archaeological record of Kültepe. Its surviving section is modest in size, but the surrounding fragments and four newly identified layers could provide important evidence for understanding the settlement’s later occupation.
The discovery does not yet reveal who commissioned the floor, what the building was used for or how extensive the original mosaic was. Continued excavation and analysis will be needed to answer those questions. For now, the find offers a fresh opportunity to examine a less familiar period at one of Anatolia’s most significant archaeological sites.
