The ROC post is situated at the top of Ruebury Hill
The hatch is not locked and the ladder still in place, i didn’t venture inside today but you can see pictures of that here
There are the remains of an aircraft post right next to the bunker.
Update May 2008 – Interior photos.
Sump pump and switches
Vintage newspaper and targets on bedframe
Original batteries (no mains) and chemical toilet
At the site of the old Portrack Incinerator, now a nature reserve
Children from High Clarence, Tilery & Norton Primary Schools in Stockton worked with local artist Andrew McKeown to design the artwork.
Warren Moor has the only standing chimney of any ironstone mine in the area, dating from the 1860s
A completely flooded 220ft downcast shaft can be seen from the path.
Between the two shafts are the foundations of a winding engine.
A vaulted roof leads from the foundations of a pumping house to the upcast shaft.
The upcast shaft is estimated to be 150ft deep, not reaching the Main Seam ironstone and not connected to the downcast hence the differing water levels in each.
A number of surface drifts can be seen on the hillside to the north east which worked the Top Seam.
As with the nearby cementstone mine at Kettleness, these are also positioned at the top of a quarry just below the sandstone cap, making for a pretty tricky scramble.
Three adjacent entrances can be found, all appear to have suffered collapses from the loose shale roof so exploration isn’t the best idea.
The leftmost tunnel slopes steeply downwards, i’m unsure if they were built dug this way or whether its just successive heaped up roof collapses leading down to the level of the original drift.
Access to the central tunnel is tighter, although a similar flat area at the bottom of the slope could be seen when I stuck the camera over the top.
The rightmost entrance has totally collapsed and only a small gap is left.
Another entrance is visible high on a ledge to the north, but access to that looks to be virtually impossible without climbing gear.
Due to its position just below the sandstone cap, this is thought to be a trial drift for cementstone, post-dating the end of quarrying in 1871. A cement works at Sandsend stayed open until 1935.
The adit only appear to be about 10m long, but the roof was flaking shale and I didn’t fancy exploring too deeply.
Alum production occurred at Kettleness from 1727 until 1871. This has radically altered the appearance of the area.
The original Alum house at beach level was destroyed by a huge landslide in 1829, what now appear to be cliffs are the face of the quarry where the sandstone over the shale has been removed.
The remains of the second alum house are on a flat area on the west side of the works, foundations remain and jet mines can be found under the platform which holds the building. The whole area is covered is loose blown shale where little grows.
The foundations of another building can be seen on the eastern edge of the site.
To the south of the building are a number of steeping pits which are slowly being lost over the cliff edge.
The remains of stone conduits used to transport liquids are also visible in the south east.
To the north of the steeping pits is the top of a cistern, again collapsing over the cliff edge.
There are a huge number of features around the site although they are often difficult to interpret due to being buried by the constantly shifting shale, they are however extensively covered in English Heritage survey AI/24/2003
This structure was unearthed by the York University Cave and Pothole Club back in 2006. They called it a mine and while there are jet mines below the Alum House, this is at a much higher level.
To me the construction looks more like some sort of storage tank and it appears to end with a wall rather than a collapse. Also the suspended wooden planks which would allow access above the liquid below.
