A tomb dating to 300-325 BC has been uncovered and is the largest ever found in Greece, the government announced Tuesday. The tomb, found in the northeastern Macedonia region, is guarded by two sphinxes, has a five-yard-wide road leading into it with walls covered in frescoes, and is encircled by a 543-yard marble outer wall. Excavations began in 2012, and the archaeologists expect to enter the tomb by the end of the month. “It looks like the tomb of a prominent Macedonian of that era,” said a culture ministry official. The tomb dates to the end of the reign of Alexander the Great, who died in Babylonia in 323 BC.
