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.
"Generally speaking, [during] the Roman Empire people built within a fixed repertoire of architectural forms," said William Bowden, a professor at the University of Nottingham, who reported the find in the most recent edition of the Journal of Roman Archaeology. The investigation was carried out in conjunction with the Norfolk Archaeological and Historical Research Group.
The winged shape of the building appears to be unique in the Roman Empire, with no other example known. "It's very unusual to find a building like this where you have no known parallels for it," Bowden told LiveScience. "What they were trying to achieve by using this design is really very difficult to say."
The building appears to have been part of a complex that includes a villa to the north and at least two other structures to the northeast and northwest. An aerial photograph suggests the existence of an oval or polygonal building with an apse located to the east.
The winged building
The foundation of the two wings and the rectangular room was made of a thin layer of rammed clay and chalk. "This suggests that the superstructure of much of the building was quite light, probably timber and clay-lump walls with a thatched roof," writes Bowden. This raises the possibility that the building was not intended to be used long term. [Photos of Mysterious Stone Structures]
The central room, on the other hand, was made of stronger stuff, with its foundations crafted from lime mortar mixed with clay and small pieces of flint and brick. That section likely had a tiled roof. "Roman tiles are very large things, they're very heavy," Bowden said.
Sometime after the demise of this wing-shaped structure, another building, this one decorated, was built over it. Archaeologists found post holes from it with painted wall plaster inside.
Bowden said few artifacts were found at the site and none that could be linked to the winged structure with certainty. A plough had ripped through the site at some point, scattering debris. Also, metal detecting is a major problem in the Norfolk area, with people using metal detectors to locate and confiscate materials, something that may have happened at this site.
Still, even when the team found undisturbed layers, there was little in the way of artifacts. "This could suggest that it [the winged building] wasn't used for a very particularly long time," Bowden said.
