Guidance for walkers: The monuments featured in this database are archaeological treasures and need to be protected and preserved - please do not disturb any sites. Please check access and firing times before visiting sites, not all sites listed are on open access land. Firing ranges and boundaries of open access areas are marked on the OL28 OS Dartmoor Explorer map. Please stick to the country code and consider giving support to the numerous agencies that help to keep Dartmoor a fabulous natural and historic environment!
About the database listings: In all listings clicking on the photo or the site name will open a page for the site with a larger photo and further details from the database. The database now has over 6680 records covering nearly all publicly listed sites on Dartmoor including around 4800 round houses. This level of detail is of interest to archaeologists but tends to swamp listings of sites more likely to be of interest for walkers. For this reason, the listings default to around 550 core sites only. These are the stone circles, stone rows and the ring cairns listed by Turner. The default search radius is 2 km. The controls below the map can be used to start a new search by entering a 6- or 8-digit reference (without the prefix "SX"). The search radius can be specified and you can add incremental Display layers of detail on top of the core sites. If using a more detailed layer you will need to decrease the search radius to avoid getting hundreds of search results.
These listings have incorporated, matched up and merged all of the records from all of the major archaeological listings including: Worth, Grinsell, Turner, Butler, Bill Radcliffe, Sandy Gerrard, Megalithic Portal, the National Monument Records and the Historic Environment Records. The author would like to thank Bill, Sandy, the lovely people both at Megalithic Portal (especially Anne Tate who did an amazing job to link listings) and at ACE Archaeology for collaborative work over the years to synchronise and correct listings across the various websites which now interlink. A culmination of years of work the final merger of cairn records took 3 months of cross referencing in 2017 the result being a snapshot of the records at that time. This data has in turn been refined since by field work and research. The round house data was supplied by Sandy Gerrard. Grid references are in order of accuracy: from Google Earth satellite, if visible and found, from a Garmin GPS reading, if visited by the author and from the literature otherwise. Individual site pages will state the source of the grid reference and provide satellite imagery. If a site listing lacks a photo it has not yet been visited by the author in which case the grid reference is from the literature.
Currently the database only includes sites which can be represented by a grid reference. Reaves are not included as they require GIS shape technology which is beyond the current capability of this system. To see the sources for the records, look at the tables on the resources menu. The database listings can also be viewed on a Google map and downloaded as GPS datasets for Garmin devices.
Corrections, or any feedback or suggestions are very welcome, email: info@dartmoorwalks.org.uk.

OS Map: SX 65203 89798

PMD: Forder Brook
ShortName: CT:Throw 6
Notes: Round cairn. Diameter 6.4 metres, height 1 metre. Cist 0.6 metres wide, oriented north-south. Central pit 1.5 metres by 1.1 metres by 0.25 meters deep. Situated on downslope edge of a natural terrace. Three edge set stones lying parallel to each other are exposed in the central pit. The two eastern ones may represent the edges of a cist with a length or width of 0.6 metres. A number of edge set stones around the edge represent a kerb. Gorse covered. NOTE: NMR gives location as SX 6519 8978.
The overgrown feature in the photo from 17/03/2025 is possibly this feature but it is a considerable distance from the NMR grid reference. That is located at SX 65203 89798

PMD: Blackaton Brook
ShortName: CT:Blackaton 1
Notes: The monument includes a cairn cemetery and sinuous linear earthwork bank situated on a gentle east facing slope overlooking the valley of the Blackaton Brook. The cairn cemetery survives as a linear cluster of six mounds standing between 0.6m and 1.3m high. Three of the mounds are circular in shape with their diameters varying between 4.5m and 8m. The remainder are oval with lengths between 5.5m and 13m. Four of the mounds have been robbed or partially excavated and an edge set stone in the centre of the northern cairn may represent the remnants of a cist.

Notes: HER reffering to Butler: Throwleigh Common cairn '5' of 7.4 metres diameter by 0.3 metres high. On the other side of the hill, out of sight of the settlement on Trowleigh Common but still within its boundaries, is a cairn cemetery which may well have been the burial ground for the hut dwellers. This southern cairn is located in a square field on the north side of the 'leat' to the west of the settlement.

Notes: HER: Bronze Age cairnfield consisting of at least 25 cairns between 0.4 metres and 0.8 metres high. Of these 14 are circular with diameters of between 3 metres and 6.9 metres. The remainder are ovoid and vary form 4 metres and 10.2 metres long. One cairn has a kerb of edge set stones this is probably a funerary round cairn. It is surrounded by a 1.5 metre wide 0.3 metre high platform. It has been damaged by robbing or early excavation.

Notes: Breton p.53 To the N. of it [Breton is referring to the Cosdon Triple row] are clitters of rocks, a short distance to the S, a swamp in which a feeder of the Blackaton Brook rises. On its E. slopes are the remains of a stone row. The feeder referred to is the Cheriton Comb which passes a boggy area. This would place the row at approximately SX 648 908. There is no known stone row at this point and this author is unaware of other accounts. This section of the Blackaton Brook has been greatly disturbed by stream workings.

Notes: "A triple stone row lies near the summit of Cosdon Hill and is 447 feet in length measured from the centre of the circled cairn which stands at the west end. At 225 feet from the west end there is a slight change in direction and the rows turn somewhat northward. This change of direction may be said to divide the row into western and an eastern section. Overall width, western part is 8 feet 10 inches, eastern part 10 feet 8 inches. The cairn is 26 feet in diameter and contains the remains of two cists; the retaining circle is very irregular. There is no formal feature to mark the termination of the rows at their eastern end"

Notes: "The Oxenham Arms, now an inn, is the former manor house and home of the Burgoyne family. A courtyard plan house, it was originally a two-room-and-through passage plan. An interesting feature is an enormous upright slab of granite built into the inner wall of the rear parlour. This looks very much like a prehistoric standing stone and it seems that the house was built around it".
