Workmen preparing the site of new public toilets have unearthed a 600-year-old sandstone watercourse, believed to have been an important feature of the Shrewsbury Abbey grounds in medieval times.
The find was made as contractors broke the ground for the new loos being built in Abbey Foregate.
Construction is due to start in the new year, and archaeologists were hired by Shrewsbury and Atcham Borough Council to keep a watching eye on the development.
The existence of a redundant Victorian culvert was known and had been recorded some years ago, and a pair of brick tunnels were duly unearthed.
Read to the end for a bit of controversy.
