“….The 15th-century Guildhall [in York] was built over a medieval road that led to and from the Ouse wharves. Common Hall Lane remains beneath the building as an enclosed passageway prone to flooding, but historians believe it was laid on top of what was originally a Roman route….”

How intriguing. As indicated in the image above, the entrance to the passage can be seen just above the level of the Ouse. It makes me think of Traitor’s Gate at the Tower of London…although loads of stone were probably brought in York, not ne’er-do-wells Anyway, Historic England want it to be opened up in the forthcoming restoration of the Guildhall.
