Nemrut’s ancient statues undergo nanolime treatment for preservation

Nemrut Mountain, a UNESCO World Heritage Site in southeastern Türkiye, is undergoing advanced conservation efforts as experts apply nanolime treatments to its ancient statues to halt further decay. The treatment targets fine cracks within the stone structures, preventing water penetration and slowing the erosion process. These colossal statues, dating back over two millennia, stand as remnants of the Kingdom of Commagene's grand sanctuary atop the mountain. The conservation initiative, which began in 2022, has continued through multiple phases, each focusing on different aspects of the site’s preservation. In recent months, teams have concentrated on restoring the head of Kommagene Tyche and the statue of Zeus Oromandes on the western terrace. Ayşe Ebru Çorbacı, director of the Gaziantep Regional Restoration and Conservation Laboratory, explained that the nanolime technique fills microscopic fissures, reinforcing fragile parts of the sculptures. She noted that early efforts yielded promising outcomes, setting the stage for ongoing improvements. In 2025, conservationists worked on reinforcing the head of King Antiochos and the eagle heads on both the eastern and western terraces. This year marks a shift toward addressing the heads of Kommagene Tyche and Zeus, continuing the meticulous process of safeguarding these historical monuments. The statues, carved from local stone, depict deities and rulers, standing tall against the backdrop of the mountain’s rugged terrain. Located approximately 2,150 meters above sea level, Nemrut Mountain is home to some of the most impressive examples of Hellenistic and Greco-Roman artistry. The site includes vast eastern and western terraces, each adorned with towering figures that reflect the cultural and religious significance of the region during the first century B.C. These statues, once part of a royal tomb complex, have endured centuries of exposure to the elements. Mehmet Alkan, director of the Adıyaman Museum, emphasized the importance of such projects in maintaining the integrity of these ancient relics. He stated that the conservation work resumed in 2026 under the guidance of the Culture and Tourism Ministry, with specialists from the Gaziantep Regional Restoration and Conservation Laboratory leading the efforts. The collaboration underscores the commitment to protecting the site’s legacy for future generations. Preserving the statues presents unique challenges due to the harsh environmental conditions of the high-altitude location. Water infiltration and weathering pose constant threats, necessitating innovative methods to stabilize the structures without compromising their authenticity. The use of nanolime represents a modern approach to this age-old problem, allowing conservators to address structural weaknesses while respecting the historical fabric of the site. The ongoing work highlights the delicate balance between technological advancement and traditional craftsmanship. As the team continues their efforts, they aim to ensure that the monumental figures remain standing as enduring symbols of a bygone era. The success of these interventions will play a crucial role in determining how effectively the site can withstand the test of time.
