Archaeologists have discovered what they believe to be the remains of a medieval synagogue underneath a kebab shop in Northamptonshire.

"Substantial" masonry walls, thought to be many hundreds of years old, were detected using ground-penetrating radar in Sheep Street, Northampton.

The National Anglo Jewish Heritage Trail (JTrails) said a structure, possibly a staircase, was also found.

The masonry walls are directly under the cellar walls of Kebabish take-away.
