Bath flytipped at Wakefield Castle
Officers from West Yorkshire Police Wakefield City and North West team made the discovery at the site of Wakefield Castle in Thornes Park while doing their rounds.
The incident was reported to Wakefield Council to be cleaned up.
Much less is known about Wakefield Castle than the more famous Sandal Castle and its mysteries are yet to be uncovered.
It is believed to have been destroyed by the great gale of 1330.
English Heritage’s records list it as Lowe Hill motte and bailey castle.
Because there is little evidence about the castle, its early history is unclear.
