Thieves on Thursday raided one of the world's greatest Bronze Age gold collections in the latest of a series of high-profile heists on European museums in recent months.

The early morning raid on Villena Museum in eastern Spain lasted just a few minutes.

A group of thieves described by one official as "super-fast and super-professional" made off with almost the entire Treasure of Villena collection, leaving behind only a few items. What happened in the heist?

"The alarm at the Villena Museum went off around 5:20 a.m.," said a spokesman for the town council, adding that within four minutes, they had all left the building again in an extremely rapid and professional operation.

The collection of Bronze Age gold, some of which we now know hailed from a meteorite, was a centerpiece at the small museum in the Alicante province.
