Road construction on the western Greek island of Lefkada has uncovered and partially destroyed an important tomb with artifacts dating back more than 3,000 years, officials said on Wednesday.

The find is a miniature version of the large, opulent tombs built by the rulers of Greece during the Mycenaean era, which ended around 1100 B.C. Although dozens have been found in the mainland and on Crete, the underground, beehive-shaped monuments are very rare in the western Ionian Sea islands, and previously unknown on Lefkada.

The discovery could fuel debate on a major prehistoric puzzle — where the homeland of Homer's legendary hero Odysseus was located.
