Greece
Every logged mystery in this country.
- Epirus
Ali Pasha's Treasure
Ali Pasha ruled Epirus from Ioannina from 1788 and was killed on February 5, 1822, in a monastery on the island in Lake Pamvotida, where he had taken refuge from the Sultan's troops. The fortune he was said to have hidden before his fall has been searched for ever since. Searchers have dug for it around Ioannina and as far away as Thessaly, and found nothing.
- Attica
Antikythera Mechanism
Sponge divers raised this corroded bronze device from a shipwreck off Antikythera in 1901. X-ray scans in 2005 showed it was a geared calculator that predicted eclipses, tracked the moon and a cycle of athletic games, and, by its own inscriptions, displayed the five planets then known. Who built it, where, and when are still argued over, and no known device matches its complexity for at least a millennium afterward.
- Crete
Phaistos Disc
A fired clay disc about 16 centimeters across, found beside the Minoan palace of Phaistos on the evening of July 3, 1908, and stamped on both sides with 241 signs from 45 different stamps. Nobody can read it. Readings have been published for more than a century and none has been accepted, while a few scholars argue that the disc was forged in 1908.
