A “winged” structure was discovered in the Ancient Roman ruins in Norfolk, England.  The mystery is that there are “no known parallels” between this structure and any of the other structures of Ancient Rome, according to the Daily Mail.  Archaeologists have found that it was built around 1,800 years ago, and they believe it is “totally unique,” according to Discovery News.

It was Professor William Bowden from the University of Nottingham and the Norfolk Archaeological and Historical Research Group that discovered the structure near the ancient town of Venta Icenorum.  “Professor Bowden explained that the building is comprised of two splayed wings around 13.5m long, which converge on a long sub-rectangular room, measuring a maximum of 18.5m in length,” the Daily Mail reports.

The foundation of the wings was made up of a thin layer of rammed clay and chalk which indicates that the superstructure or most of the structure was made of light materials which could be an indication that the building was not meant to be used long-term.  Researchers found that after this “winged” structure was destroyed, another building, this one decorated, was built over it.  Bowden said that few artifacts were found at the site, and none of them could be linked to the “winged” structure.

Another fact that adds to the mystery of the structure is that before the Romans conquered this area, the Iceni lived there; this structure could have been constructed by them.  Bowden says, though, that Iceni architecture was very simple and the “winged” structure is too elaborate to have been constructed by them.

This “winged” structure is out of character for both the Iceni and the Ancient Romans so Bowden and his team are perplexed as to who this structure belonged to.
