A recently discovered mysterious "winged" structure in England, which in the Roman period may have been used as a temple, presents a puzzle for archaeologists, who say the building has no known parallels.

Built around 1,800 years ago, the structure was discovered in Norfolk, in eastern England, just to the south of the ancient town of Venta Icenorum. The structure has two wings radiating out from a rectangular room that in turn leads to a central room.
