Man Road Ditch

Looking south towards Man Road Ditch and Knowl Hill, Photo by David Mercer.

Even the name is mystery, “Man Road Ditch”. The ditch is of unknown date and unknown purpose and runs from the foot of Knowl Hill in a NNW direction.

The earliest reference found so far, is in the first series 6″ OS map (1851) of the area.

The feature that crosses it at the bottom of the image is the turbine access road!

Archaeological Site Location and Survey


With many major and minor sites unrecorded SE Lancashire is the most exciting area in the UK if you want to discover archaeological sites. Don’t believe it? well I even had to get a 2 metre high medieval cross put on the Sites and Monuments register a few years ago, amazing but true.  It is at Doffcocker near Bolton and is in the grounds of the church. The local paper was very helpful in tracking background information to the cross, which had been moved from a previous location, a bridge over a stream!

Remember SAW

When looking for an archaeological site check SAW!

Soil – was the site on good soil or were there mineral deposits like coal or marl?

Aspect – Was the site facing the south and was it sheltered or on a hilltop?

W – Water was vital for farming and survival and also a source of power for water and fulling mills.  Water (streams, rivers and lakes) could be a place to catch fish! In some places in Lancashire water was used as a defence in the form of a moat, even Prestwich Rectory had a moat and this can clearly be seen in the first series OS map in the mid 19th C.

Clues in the Landscape

Banks and ditches and old boundary walls are good indicators of rural archaeological sites. You may even see some stones where a building has decayed and probably had stone robbed. Wooden structures are unlikely to have left clues above ground but sometimes a moat survives, or was evident, at Prestwich Rectory (Old site not the one near the church) for example.


Place-names sometimes give clues for archaeologists, indicating an archaeological site a good example is the place-name “castle” as in Castleton in Rochdale. Yes, Rochdale had a Norman castle, but nothing is visible today.

Archaeological Finds

The chance discovery of finds may sometimes indicate an archaeological site. However valuable finds were often hidden away from the main site, burial sites being the exception to this. Usually it is the mundane finds which indicate an archaeological site. These can be found on the surface of a ploughed field or a stream.

Aerial Photographs

The Web has made access to aerial photographs easy, given a low angle of sunlight it is possible to see banks, ditches, roads and old cultivation marks which may indicate a nearby site.

Sites such as Google Earth have a wealth of information, Ssince photos were taken at different times of day the angle of sunlight varies and so will the visibility of features. Try viewing different views of the same site and different dates, try comparing the views from different sites.

Older photographs can show sites before they were ploughed or built on and show changes over time.

Historical Records

Medieval deeds, charters, court records and wills give many valuable clues to finding archaeological sites. Many deeds and charters are still to be translated from the Medieval Latin. Salford Hundred has a large number of untranslated medieval documents, many refer to boundaries and sites that remain undiscovered.


Getting out in the landscape and surveying sites is the essential work when discovering sites and it is the vital drawing together and evaluation of all evidence that might indicate an archaeological site.

Low Sunlight Highlights Ditches and Banks


Always start with the most mundane theory for your site and work your way logically through other interpretations of what you have found.  Many antiquarians from the region were inclined to see many sites as ‘Roman’  rather than post Roman.


The geology of the region is complex and many natural features have been seen as archaeological sites, could your ‘site’ be glacial in origin? Sound geological knowledge is a vital part of any archaeological research and geological research must be undertaken for each site.


The local ecology is also vital in assessing archaeological sites, the climate has changed over time. If evidence of early vegetation survives there may be clues to human activity, such as forest clearance, or evidence of agriculture.


Folklore is not reliable, but sometimes it may indicate a site, or at least give an interesting background to the the site and landscape you are researching. The name ‘castle’ is one of the more common indicators of an archaeological site.


Make sure you act responsibly when accessing a site, respect landowners and the environment. Work with local communities to further the knowledge of and protect your local heritage.

Surveying What You Find

Archaeological survey requires many skills and a holistic approach, a team of experts is needed to really assess the potential of an archaeological site. Included in this team is the local expert, who knows the landscape and local history of the site in question. Publishing and professionally reviewing information is crucial in getting discoveries accepted and advancing archaeological knowledge.

With so little published archaeological survey and research work undertaken in SE Lancashire, the area offers many opportunities for researchers.

A detailed survey of SE Lancashire (Salford Hundred)  has yet to be undertaken as regards archaeology.

Some ideas for research

  • Urban archaeology – Rochdale, well documented yet little excavation has taken place into medieval Rochdale.
  • Survey of the Pennine foothills and the Moors, many cairns are still unrecorded.
  • Inventory of unpublished excavations.
  • Geophysical survey strategies and benchmarking (which techniques are best suited to local soils?)
  • Surveying rural sites mentioned in medieval documents.
  • Survey of moorland enclosures and assarts.
  • Boundaries in the landscape, from ditches and banks to early stone walls.
  • Pollen analysis, to reveal human impact on the landscape and vegetation over time.
  • Early iron working
  • Early coal mining.
  • Excavations to confirm the nature of particular sites.
  • Moated rectories of Salford Hundred, myth or reality?
  • Priorities for archaeological research.
  • Comprehensive update of archaeological sites on planning GIS (Graphical Information System).
