Hi Pauline!
Tunnels are very intriguing! one of the old Hall tunnel entrances was at the side,was very low,about 3ft high,if I remember correctly,and typical scrolled cathedral arched lintels..nicely carved out of sandstone,and weathered to hell,which, seeing as it was a few hundred years old,you would expect it to be.
If you walk down Bedlington bank,go into the picnic field [Attlee Park],then walk left and under the river bridge,going downstream,about 70 yards along,on the bank sides,you will see the entrances to tunnels on each side of the river,with nice stone arches.
Now a lot of years ago,flat-bottomed barges used to travel up the river carrying all-sorts of goods,cos the river was a lot deeper than it is now.
There was a set of differences between us lot as to the origin of the tunnels,and King John's stay overnight at the old hall.
It makes no difference ,cos none of us were there,and we only go off what we have been learn't by other people in life!
You wouldn't be the canny young lass who met my Wife and me down the Furnace Bank,one day,and who expressed an intense interest in tunnels........would you?
We met at a later date,same place,and this nice lass and her partner/Husband/Friend?....had been exploring the tunnel entrance......not you?...!!!!
