Show on map The 16 arches of the old kilns are as prominent in the valley as the new kilns also being around 90m long.
There are 4 kilns with 4 arches each, the arches are about 4-5m wide.
The upper parts of the kilns have gradually collapsed and are spilling out through the arches.
Above the arches is a ventilation chimney associated with the mine, which stands 7.5m high with a small door at the base allowing a view inside.
Show on map The three large bays of the calcining kilns are about 90m long and can be easily seen from all around the valley.
The iron ore mined here was carbonated which required calcining before smelting.
In one of the bays the retaining wall which looks to have been anchored with large wires has collapsed, the faces of wall were once lined with wrought iron which was removed when the mine was abandoned.
Ironstone and coal would loaded into the top and calcined ore drawn out from the bottom, It has been estimated that each kiln could produce around 2000 tons of calcined ore a week using about 80 tons of coal. In a more complete bay the top courses of fire bricks are balancing precariously on small pins.
There are four small tunnels / flues entering the faces of the bay at the base.
Show on map The remains of a house complete with chimney and fireplace still stands by the track before New Kilns.
Show on map There are substantial remains of a row of cottages above the New Kilns, known by some as Black Houses although I think that might just relate to buildings closer to the main track.
The mines and railway closed between 1926 and 1929, so presumably the cottages were abandoned at the same time.
Directly adjacent to the cottages are a block of workshops.
Show on map A single wall remains by the side of the track, the stucture once held a water tank for trains on the Rosedale Railway
It can be easily located walking down from the Lion Inn
Show on map The culvert tunnels through a sizeable embankment at the head of the valley, and carries the River Seven under the railway.
The tunnel must have been built some time before 1865 when the line opened, but is still in very good condition
Show on map The entrance can be easily located by crossing the stepping stones near the old mill and travelling towards the viaduct on the south bank
The brickwork around the entrance is under attack from the trees
Inside the tunnel is in good condition, although muddy. The dark red line on the side suggests it may have been deeply flooded at some point in the past.
In the stream outside there is a row of bricks with some discoloured water leaking out, perhaps some sort of drain from the drift.
This drift is a failed drainage level for Longacres mines.
Show on map A brick cap stands around the downcast shaft, the upcast is a short distance away but filled and obscured by undergrowth.
The remains of another building can be seen adjacent to the shaft, the engine based of the winder associated with the shaft.
Show on map The powder house dates from around 1877 and is of a very similar design to the one at Eston, its also extremely overgrown and dirty and looks to be the haunt of young drinkers and wire burners.
Show on map The trackbed of a railway can be seen on the map, running from Swainby directly up to the mine entrance, what appears to be an old rail carriage is being used as a shed near the roadside.
Following the direction of the track a short distance into the woods leads to the mouth of two small tunnels.
One tunnel was for ventilation and the other the main drift, both are full of water and filled with earth a very short distance in.
There are a number of depressions behind the tunnels where the workings have collapsed, the remains of a ventilation shaft are marked higher up the hillside, a large spoil heap without vegitation is also very prominent.
The ironstone mines operated from 1857 to 1887 in this area
