An introduction to Swill Tor, plus some other local names .....
Rev. Bray 1831 ..... writing on May 17th, 1831, about an excursion on Dartmoor Railroad i.e. Tyrwhitt's 1823 Plymouth & Dartmoor Railway. In: Mrs Bray (1836), The Borders of the Tamar and Tavy, Vol 1 of 3, page 279 .....
|"Yeast Tor" above no doubt refers to the
diminutive Yes Tor at SX 5637 7259, in the area of Yestor Brook,
Yestor Bottom and the ruined Yestor farm. The latter has been traced
back to a lease in 1673 when it was referred to as Yeastor aka Easter
Source: Mike Brown (2001) Guide to Dartmoor, CD-ROM, Dartmoor Press, Grid Square 5630 7279: Revd. Bray's mystery name solved! Yeast Tor = Yeastor = Yestor (originally East Tor).
Crip Tor (left) and waste tips at Swell Tor (right). The track up the middle is the old tramway from Foggintor that branched off the 1823 Tyrwhitt horse-drawn PDR - Plymouth & Dartmoor Railway. The feature across the photograph, near the camera, is the old 1883 GWR-Princetown Branch Line. The track runs straight to the top of Swelltor Quarry and has two side branches running left, around the hill. The first side-branch (hard to see here) ran to Sailors Home Quarry. The second branch, which this walk follows, and is seen in the photograph, runs left to Crip Tor Quarry (this being the quarry into Crip Tor). These are both seen in the photographs below. There is another Criptor Quarry, near Criptor farm, at SX 5587 7295. The photograph was taken from beside siding that runs to Big Tip, at Foggintor.
Granite setts in the track that once bore the iron rails that guided wagons carrying granite. These were presumably guided down by horses taking the strain of the weight of the loaded trucks. Fixing holes for the fishplates that bore the rails can be seen some setts .....
As previous photograph.
The track approaching the tor.
A closer view - this rocky tower can be seen later as a landmark at the top of an inclined plane that ran down the other side of the tor, again to the old railways.
Inside Crip Tor Quarry, although probably more properly called Sailor's Home Quarry ..... we are standing more or less on the end of the tramway track ..... not much of the tor remaining .....
A sturdy gunpowder store in the quarry, possibly used as a shelter during blasting .....
Side view of the powder store .....
Looking into the quarry below - this is Sailor's Home Quarry (Hallett, map p.63, p.69), and the first (lower) side branch off the tramway going straight up Swell Tor ran around the hill into the far end of this view, close to the cleft in the rocks. The old 1823/1883 railway trackbed (pale coloured) can be seen clearly down the hill. Just to the right of the cleft, at the far end of the long workface on the right, is the access to the inclined plane that runs down to the 1823 / 1883 railway.
A diversion to look into this quarry, not made on the group walk .....
The double "wall" at the right edge of the photograph is at the top of the inclined plane .....
View into Sailor's Home Quarry .....
Inclined plane with some granite setts in
situ ..... there are stone-lined drainage channels in the plane, mostly
Devon & Dartmoor HER - MDV80767 - Plymouth and Dartmoor Railway, inclined plane
Crip Tor at the top of the inclined plane .....
Crip Tor "stack" as a landmark.
Back to the group walk .....
Another view of the explosives store.
View over to the large quarry at Foggintor, with North Hessary Tor transmitter mast beyond and with Hollow Tor (far left).
Zoomed view to Ingra Tor with its quarry to the left and the old railway track-bed running across the photograph. The track behind the tor appears to be that running down towards the northernmost of the two circular pounds at Routrundle.
Overview, and today's best, view of Swelltor Lower Quarry; the entrance is hidden in a cleft at the extreme left - and another same-sized quarry is hidden through an entrance to the right - see the next photomontage. Click the image to see a larger version.
Swelltor Upper Quarry - the view is through the connecting cleft to the lower quarry looking down towards the Smithy's Shop. Click the image to see a larger version.
There is a built structure In the centre of this photograph of the lower quarry in the area that on the old map was a "railhead", or end of the tramway out of the quarry .....
Closer view of the possible loading quay.
Remains a building, SX 55982 73237 - it
has a good view of the far-side workfaces; possibly matched by a similar
structure across the quarry in the next two photographs? It might be
part of the original Smithy, shown in the 1883/1885 OS map?
OS 25 inch single sheet England and Wales, 1841-1952 (surv. 1883/publ. 1885) - original Smithy uphill beside (or in) the quarry.
This map also shows the apparently abandoned Swell Tor West Quarry. It also shows the "Upper" quarry to be larger than the "Lower" quarry, and therefore older.
View across the entrance gully into the quarry to another man-made structure on the cliff top .....
Two sett makers' bankers, where stone workers chipped away at rocks to make the setts that carried the tramway rails - there are telltale piles of rough chippings.
The Manager's House, beside the siding: the Blacksmith's Shop is beyond, with standing walls .....
The Foreman's Office, SX 55920 73164, on the right bank when entering the quarry, looking across the main track at the Manager's House. The Blackmith's Shop is at the upper right edge.
View into the lower quarry ..... showing
the cleft into the upper quarry.

Drill testing stone.
The Smithy .....
View from the back of the Smithy - where the famous Swelltor dinosaur makes an appearance .....
Swelltosaurus roccus - possibly a large relative of Scutellosaurus.
Loading Quay beside the Swelltor railway siding.
Engine House features.
This is the site of the Crushing House for making stone ballast; just beyond this structure is the Engine House.
Wooden sleepers on the branch line siding
from the GWR into Swelltor Quarry, still with fixing nails in place

Another view of the nails.
Apparently these are practise work pieces made by apprentices, left on the railway bed.
This covered square building was found at SX 55835 73366, during the 2nd reconnaissance walk in the clitters and waste tips above the weighbridge area - not an easy area to explore.
Site of the weighbridge, SX 55745 73291 - the old smithy walls can still be seen in the distance, on the right.
The famous Swelltor corbels (twelve of them left here), 650 were cut in 1903 for the widening of London Bridge. The bridge, "New" London Bridge, was designed by John Rennie, opened by King Wiliam IV and Queen Adelaide, in 1831. It was bought by American, Robert McCullough, in 1968, and re-erected in Lake Havasu City, Arizona.
Some recent history of the time .....
- Grace's Guide - "The bridge was widened to 65 ft in 1902"
1902 - In 1902 plans were finally put into action and the bridge was widened. The alterations added four and a half feet to each footpath, and two and a half to the road
1904 - "Built in 1831 and widened in 1904".
1902-1904 - "London Bridge was widened in 1902–04 from 52 to 65 feet (16 to 20 m), in an attempt to combat London's chronic traffic congestion. A dozen of the granite "pillars" quarried and dressed for this widening, but unused, still lie near Swelltor Quarry on the disused railway track a couple of miles south of Princetown on Dartmoor"
Why are they still here? There has long been conjecture that they were either cut too short or that they were stained with iron (Hallett p.60, K Brewer p.56, Hemery p.1029-1030.
Brewer (p.51) gives their dimensions as noted in The Stone Trades Journal, January 1904, as "The length of each is 10 feet by a depth of 3½ feet, and an average width of 1 foot 6 inches, and each has a clear projection or length of leverage 5 feet 6 inches".
Hemery (p.1029-1030) states: "Each measures 9 feet 6½ inches long, 1 foot 3½ inches wide and 3 feet 7 inches high from base".
Measuring them is not easy because their "inner" ends are rough and miss-shapen. Ten feet = 120 inches, but I measured five as being 110, 109, 110, 109 and 109 inches long, compared to Brewer's specified 120 inches and Hemery's 110 inches long. They are too short?

SX 55445 73643 - the remains of two wooden beams embedded in the ground mark the site of the old Points Shed that used to be painted yellow. The points controlled access from the "main" line (coming diagonally from the top right) to the Swelltor siding (running back centrally, left of the "main" line). Apparently, the shed was painted yellow.
SX 55435 73758 - Swelltor siding buffers, at the north-west end of the siding .....
Another view of the siding buffers with a "main" line bridge in the background that allowed livestock to cross the railway ..... this is seen in the map linked in the previous caption .....
SX 55385 73786 - the bridge ..... with two gateposts .....
Clever captive gatehangers that prevent the gate being removed ..... one up, one down .....
King's Tor, at SX 55657 73876, seen through the bridge. Between the bridge and the tor, lies King Tor Quarry - this was the objective of the 1823 Tyrwhitt P&DR tramway, to carry granite to Plymouth docks from the "King Tor Quarries". The line probably went around the tor as far as Foggintor because this was believed started in 1820 under the name of "Royal Oak Quarry". It was extended to Princetown in 1926.
An aside: three photographs from the 2nd reconnaissance walk on 15 July, from Swell Tor summit to Kings' Tor .....
The abandoned face of Great King Tor Quarry, this faces left, west, down to the railway line .....
Looking down the quarry, to the railway line, marked by the tree and the railway bridge (actually a cattle "creep" to allow livestock access to the area .....
A zoomed view to the railway bridge.
..... and back to today's walk .....
Little King's Tor logan stone, SX 55345 73915 .....
Little King's Tor, located between the 1823 Plymouth & Dartmoor Railway and the 1883 GWR Princetown Railway trackbeds .....
This is where the 1823 tramway (running straight away from the camera, on the right) looped out with a tight bend around Little King's Tor using horses and shorter wagons whereas the 1883 steam locomotives and no doubt larger wagons had to cut a more gentle bend through the tor (on the left of the photograph) .....

Base of railway platelayers' hut at SX 55477 73986, just past where the two railways merge together .....
Last photograph - of the hut base, the railway junction and Little King Tor with its logan stone.

This walk was reached using the B3357 and between Tavistock and Two Bridges. Car parking was at the small quarry seen on turning into the track to Yellowmeade Farm the P symbol on the map and across the road from there, by the ruins of Foggintor Mission Hall. There is also some space up the hill at the old Pump House.
