The Greek Ministry of Culture unveiled the fully restored interior and monumental perimeter wall of the Kasta Hill Tomb in Amphipolis, revealing its true scale and historical connection to the era of Alexander the Great. The announcement followed the completion of restoration work and archaeological excavation in the north of the country. The culmination of this phase of work exposes, for the first time, the largest funerary complex discovered in ancient Macedonian territory.
Technical teams completed the structural stabilization of the chamber’s vault and removed the old scaffolding that had been blocking researchers’ views. Dating from the last quarter of the 4th century BCE, this monument surpasses in scale the Great Tumulus of Vergina, the royal Macedonian necropolis at ancient Aegae.
The architectural complex stands out for the sumptuousness of its materials and the massive use of marble blocks imported from the island of Thasos.
Greece’s Minister of Culture, Lina Mendoni, visited the archaeological site to oversee the final stage of the conservation project. She described the monument as a unique and magnificent work from antiquity. The local government plans to integrate the tomb into the region’s international tourist routes.
A marble wall that protects history
The perimeter wall extends for 497 meters (543.52 yards) in length around a central mound that covers 8 hectares of land. At 140 meters (459 feet) in diameter, the structure is exceptionally large even by the standards of ancient Macedonian necropolises.
Restorers reconstructed a 105-meter (114.82-yard) section of the southern wall using original marble fragments found on the site. Engineers also installed a drainage system to shield the hillside from rainwater erosion. The tomb’s original design resembled a circular fortress intended to withstand the test of time.
The recovered artistic jewels
Specialists restored the missing heads and wings to the two colossal marble sphinxes that guard the main entrance to the tomb. Inside the chambers, experts stabilized a mosaic depicting the mythological abduction of Persephone. The floor features an intricate design executed with natural pigments.
Workers installed a replica of the monumental double-leaf marble door to seal the main burial chamber. The splendor of these elements confirms the work’s close connection to the family circle of Alexander the Great.
The mystery of the figure buried
The exact identity of the person buried in the tomb remains under scientific investigation. Archaeologists suggest that the monument held the remains of someone very close to the Macedonian conqueror. The leading hypotheses point to his mother, Olympias, one of his wives, or a high-ranking military general.
Three of Alexander the Great’s most celebrated generals—Nearchus, Hephaestion, and Laomedon—resided in the ancient city of Amphipolis during this period. The city’s military garrison maintained its unwavering loyalty to Olympia after the monarch’s death in 323 BCE. The lack of written inscriptions on the walls of the tombs makes it difficult to confirm the deceased’s name.
Opening to the public in 2028
The Ministry of Culture’s development plan envisions a controlled opening of the monument to the general public in early 2028. Authorities are currently constructing an exhibition space on the eastern side of Kasta Hill to house the recovered original artifacts. The project aims to boost the local economy through sustainable cultural tourism.
To enhance the experience, several technical institutions completed the high-resolution, three-dimensional digital recording of the reliefs painted on the marble. These virtual models will allow visitors to interact with the decorations without damaging the monument‘s physical structure. This technology ensures the long-term preservation of this World Heritage Site.
