I am interested in Enigma's reply to the query about the crenelated wall on Bagnall Road. I have been trying to find out more about it as I live just round the corner from the wall. I have also read about the skeletons discovered in 1937 on the site and have been trying to find the source of this information, without success! Can Enigma let me know about the source of the information about the excavation in 1937 please? Thanks!
