The Roman Road from Manchester to Ribchester

Margary Number: 7b

Distance: 26.5 miles

Considered by many to be the original Roman route north linking two of our most important forts. As we shall see below there was almost certainly an intermediate fort splitting the distance almost in two.

A feature of the road is the use of long sighting alignments - indicative of military planning no doubt. The first alignment is on Affetside, the second on Rushton's Height, the third on Top of Ramsgreave and the final one, not on Ribchester, but on Jeffrey Hill. We now have some evidence as to where the first alignment was set out at the Manchester end.

Roman Manchester Road Map

A road issued from the north gate of the Manchester fort but this was more likely a connecting road to the main road which probably underlies Deansgate. The road from the fort made a shallow angle with Deansgate, the two coinciding around half way along, about where Lloyd Street is today. Deansgate was labeled "Roman Road" on the 1896 OS 25-inch map.

At the north end of Deansgate, in the Cathedral area, the road swung around the River Irwell. The remaining route was remarkably direct based on inter visible high-points: The first was to Affetside (273 metres high) between Bolton and Bury. It was most likely sighted from Broom Hill at Higher Broughton at the Manchester end - see later.

Sighting from Manchester or more accurately Salford, to Affetside might seem difficult today but would have been feasible in Roman times - no pollution or high rise apartments then.

Ordnance Survey First Edition Map - Broughton

On the first alignment parts of the modern highway (A56) represents the course and the former Roman Road Terrace provides the first clue!

Contour Map - Setting-Out position of the Affetside Alignment, Higher Broughton

There was a subtle dog-leg to get to Broom Hill, Higher Broughton and this is where the straight alignment to Affetside really begins.The old name of Broom Hill gives us a clue as to its suitability for sighting all the way to Affetside and it is therefore the logical position for the Romans to set-out their first main alignment.

OS First Edition Map - Broom Hill

Broom Hill would appear to have been around 200 feet AOD. Presumably the horseshoe bend in the River Irwell will have moved much closer since Roman times and eroded much of the west side of the hill.

Setting-Out position of the Affetside Alignment, Higher Broughton - 3D View

It is impossible today to see if Affetside is visible from here as at ground level buildings get in the way. This Google Earth 3D view gives the impression that it would be. The image is an animated gif with and without the Roman road overlaid.

Broom Hill (the house) has gone but Broom Hill Lane is still there but now shortened to just Broom Lane.

Lidar Image & Map - Whitefield Golf Course

This appears to be the first extant stretch of the Roman road from Manchester. The agger has survived just in front of a green on Whitefield Golf Course.

The line is a little to the east of where the OS first edition recorded it but now explains why trenching here by University of Manchester Archaeological Unit in 2008 did not find the road on the OS line. This was in connection of development of a parcel of land, formerly the site of the old clubhouse and putting green. The agger visible in the Lidar indicates the road was just east of the OS line and trenches. Thanks are due to Norman Redhead for this information.

Paradoxically Bury New Road in places follows some of the the route. This seems to be the case of a turnpike road being built, at least in part, on Roman foundations. Bury Old Road is further to the east near Heaton Park and despite its name is not really therefore the older route.

Crossing the River Irwell

The Irwell at Radcliffe was the major obstacle on our road and it is likely it would have angled down to cross the river although the OS First Edition map indicates it carried straight on. This seems very unlikely given the steepness of the drop down so a dogleg via Goat's Gate is much more logical and typical. The OS surveyors got crossing routes wrong on this road at the Hodder, Whiteray Beck and the River Greta!

The first long length of surviving agger begins north of Radcliffe either side of the Manchester, Bolton & Bury Canal and heads up towards Ainsworth via Withins Reservoir..

Between Bury New Road and Ainsworth Road there is modern housing with a street name Watling Street. It is though somewhat to the east of the real Roman road but at least the traditional name is preserved.

Cockey Moor Road and Cockey Moor are names that for many years made this spot the leading contender for the location of Coccium. The Roman road can just be made out across Cockey Moor before the Lidar data runs out.

Manchester to Affetside - Route Map

At the high point of Affetside the first alignment ends and the road changes direction slightly to negotiate the Edgworth Valley.

We are now on the second alignment heading towards Rushton's Height. However, the Roman road deviates off the alignment several times adapting to the contours to get through the Edgworth Valley.

Lidar Image - agger leading to Pelton Fold

This was the last definite stretch known approaching Pelton Fold before the Road was lost under Edgworth village. Lidar has extended beyond it beyond Pelton Fold dropping down to the cross Quarlton Brook near the modern footbridge.

Roman Road Excavation 1950s - Knott's Brow (on the Pelton Fold stretch) - 1

In the 1950s, Chris Aspin led a group from the Helmshore LHS which excavated a section of the Manchester to Ribchester road to a field at Knott's Brow, near Edgworth. This is the length heading to Pelton Fold in the lidar image referred to above.

Chris has kindly supplied copies of a cross section drawing and an annotated photograph.

As can be seen the agger was still prominently cambered in the middle.

3D Oblique Lidar Image - Edgworth

There are signs of the road climbing up from Quarlton Brook. It then must then have passed close to the Barlow Institute and continued on via Horrocks Fold and slightly east of Horrocks Road north of this, before rejoining the main road heading for Hob Lane Bridge.

3D Oblique Lidar Image - Wayoh Bridge Fort Site

Whilst searching for the course of the Manchester to Ribchester Roman road around Edgworth, I spotted the outline of a probable Roman fort at Wayoh Bridge.

A check of various data sources revealed that ditches at this site had been recorded previously (1980s) and was logged in the PastScape database somewhat optimistically as Coccium, No. 44354. This referred to "The south-west and south-east sides of a probable ditched enclosure with rounded corner is visible on air photographs on one side of the Ribchester-Manchester Roman road.." It added " ....visited by Farrar in February 1981, who was unable to reach any positive conclusion about the earthworks." They didn't have Lidar then!

Lidar Plan - Wayoh Bridge Fort

LiDAR has provided that positive conclusion and clearly visible is the probable outline of a small fort with double ditches on 3 sides, single ditch on the road side and 3 rounded corners.

The Roman road from Manchester to Ribchester passes the fort on its south-west side and the fort's location on a headland before the descent to Wayoh Bridge is an excellent one. It has superb views both north and south along the Edgworth Valley. The site lies approximately 14 miles from Manchester and 12 miles from Ribchester making it a logical location.

There are traces in the LiDAR data of an internal feature (building?) that respects the orientation of the fort. Also noticed was a water supply for the fort coming down alongside Moorside Road.

Wayoh Bridge Fort - South-West Corner

Visits to the site have confirmed its suitability for a fort with the ditches evident and 3 of the rounded corners detectable. Often with LiDAR finding the features on the ground can be difficult but not here. The fort platform measures in the order of 75 metres square and could be described as either a fortlet or small fort. The double ditches are perhaps a bit unusual and could indicate two phases with a later reduction in size - possibly similar to Castleshaw which also lies at a very similar distance from Manchester (13 miles). There are traces in the LiDAR data of an internal feature (building?) that respects the orientation of the fort - see the LiDAR plan. Also noticed was a water supply for the fort coming down alongside Moorside Road.

Wayoh Bridge Fort - Southern Ditches and Rampart

The ditches on the south side are the easiest to find on the ground and the rise up to what must be the south rampart is even more obvious.

The double ditches are perhaps a bit unusual as they are somewhat widely space. This could indicate two phases with a later reduction in size - possibly similar to Castleshaw which also lies at a very similar distance from Manchester (13 miles).

Lidar shows the road continuing west of Blackburn road north of Wayoh Bridge before merging in the modern road at Pike House.

3D Oblique Lidar Image - Grimehills Bridge looking north to Rushtons Height

The Ordnance Survey first edition show the Roman road heading straight at Grimehills Bridge but on close study I think the modern road probably marks its actual course.

Beyond Grimehills Bridge the modern road wanders off the Roman line on its east side for a short spell.

At Rushtons Height at the top of the image, the road will make another turn onto the next alignment aiming for the Top of Ramsgreave.

Blacksnape, Nr Rushtons Height - looking North

It needs a very clear day to prove it but these long setting-out alignments were perfectly feasible. The final alignment change at Top of Ramsgreave is exaggerated in this telephoto shot - the actual angle change is only 1 degree for Jeffrey Hill.

I have shown the line as straight on the photo but there is Lidar evidence that the Roman line could well be slightly further to the left (west) here on a line through the Red Lion Inn (cream gable ended building). There is a local folklore that the road is visible in the cellar.

The Roman alignment leaves the modern Blackburn Road at Hoddlesden Road. In July 2005, Darwen Archaeological Society excavated to try and find the road at Brocklehead Farm but were unlucky. Lidar indicates the road is in the recorded position but has been much disturbed and removed in several places.

Top of Ramsgreave - looking South

Looking back to where the previous photo was taken. Blackburn lies out of sight over the hill with the church tower.

This is the first visible trace north of Blackburn with agger showing as a lighter shade of grass. What also is evident is how big it is - this was a major Roman highway.

Top of Ramsgreave - looking North

Ribchester is down in the valley bottom but the road is aligned on Jeffrey Hill now. It can be made out by a series of hedgerows most of the way to Jeffrey Hill.

Note: Jeffrey Hill can also be spelt Jeffry.

Possible River Ribble Bridge - Ribchester

The site of the Roman bridge at Ribchester over the River Ribble has been the subject of much speculation. With the advent of Lidar we can now make an informed guess at to where it could well have been located. The route of the road down to the Ribble valley from Manchester and that of the road to York are visible in the Lidar data giving strong clues as to the bridge's possible location. Also visible is the probable linking road from Ribchester near Beech House. Note there is no evidence for the road from Manchester bypassing Ribchester and continuing on towards Jeffrey Hill. To get to Jeffrey Hill and the north then a diversion into Ribchester was evidently necessary.

Despite these clear indication of the roads approaching the bridge site, the big unknown remained - where precisely was the river? Clearly is has moved over the centuries - witness the destruction of around 1/3rd of the fort itself. However, also visible in Lidar are earlier courses of the river, perhaps those dating from Roman times. Given that the roads would have been aligned on the bridge then its position can be surmised and a probable location for the Roman Bridge (see right). Given the southwards movement of the river, then the northern abutment would represent the best chance for survival. But would there be any supporting evidence on the ground?

Lidar Image - link road to Ribchester at Beech House

Fortunately, in December 2016, the opportunity arose during a watching brief at Beech House to explore the possible bridge locations. Thanks are due to Nigel Neil and the landowner Mr Paul for their help and assistance. There were traces of an agger at two spots and where the bridge approach was surmised there was a large assemblage of stones including one dressed sandstone block. There were none elsewhere. Does one dressed stone make a bridge? Probably not but it is a logical position for a bridge bearing in mind the alignment of the roads and the possible old river course there. The coordinates of the possible bridge's north abutment would be SD6566 3522.

Looking East towards the possible bridge location, East of Beech House

The agger is very obvious and definite here but it doesn't aim for the bridge abutment. This at first may seem strange but for there would have to have been an approach ramp to get up to bridge deck level. So the stone area would not represent the actual bridge just its approach. The bridge abutment would by alongside the river channel.

Ribchester Roman Road Map

We can now complete a Roman road map of Ribchester with reasonable confidence. The original fort was further north than the later stone fort and the road layout was clearly designed/set out for the first fort. Disregard the Ordnance Survey line shown on the map for the road to the east.
