Thanks to jST, jimmy9092 and The Amateur Wanderer for posting pictures of this place. I got a few pictures of the ovens working "over the fence" just before it shut. Sad to see the last one go. I'll have to sniff my bottle of coal tar shampoo to bring back the memories...
Hargreaves said that they were keeping on around 20% of the workers for a few months to help decomission the plant so it isn't going to be totally abandoned just yet, even though the ovens are now shut. There is quite a lot of valuabe coke, chemicals and equpiment on site that will be removed and sold before the place is finally demolished.
