I saw this on NatGeo! It's so incredible. Evidently, another hobbyist or archaeologist had been in the same place only a few weeks before... I'd hate to be that guy. But yeah, it's Dark Age period, so it explains why it wasn't recorded, what I don't get is what it was, really. Some say it was a Pagan-Christian battle that the Pagans won because of the crumpled golden cross. The only parts that were in this stockpile were valued golden pommels, spearheads, etc., leading one to believe that it was loot. Very interesting!
If I were to make something out of LEGOs, I would probably use LEGOs. Pretty advanced stuff going on up in my head.
