There was a tunnel discovered recently up in the grounds of the old childwall college.

I believe as mentioned previously on here that the Childwall website is Jona76
A tunnel was found when the foundations were being laid for the new garage that was built last year in the old shell of the equestrian building in all that remains of childwall hall.

This was discovered when some of the old blocks of sandstone and york stone were lifted off the floor.
the tunnel was found with a lot of earth in and was filled in and the work carried on.
My friend works in said garage and I work away so was pretty gutted as i didnt get to nose any further.
