They ruled out the possibility that the tomb could be that of Alexander - the emperor is believed to have been buried in Egypt after he is thought to have died of a fever in Babylon in 323BC.
The tomb was found in Greece's northern Macedonia region, from where Alexander began to forge his empire. Archaeologists, who began excavating the site in 2012, hope to fully explore the tomb by the end of the month to determine exactly who was buried there.
The site is being guarded by police while archaeologists continue their work. Catherine Peristeri, head of the ancient monuments department in northern Greece, said that some of Alexander's generals and admirals had links to the area around the city of Amphipolis. It was also the place where his wife, Roxana, and son, were killed in 311BC on the orders of Cassander, a Macedonian general who fought over the empire after Alexander the Great's death.
Situated about 100km northeast of Greece's second-biggest city, Thessaloniki, the tomb appears to be the largest discovered in Greece, and probably belonged to a prominent Macedonian of that era, a Culture Ministry official said. The tomb, which consists of decorative white marble and frescoed walls, was partly destroyed during the Roman occupation of Greece.
Amphipolis was founded in 437BC as an Athenian colony, but was conquered by Philip II of Macedon, Alexander's father, in 357BC.
Alexander the Great single-handedly changed the history of the ancient world with a lightning pace of conquest.
