6/7 This plot shows a wider context for the long barrows near Morestead (circled), showing the they are part of a cluster of long barrows on higher ground bracketed by the Itchen and Meon valleys

5/7 The three long barrows that cluster around this valley are compared in the following plot, showing their contrasting nature

4/7 Taking a slightly wider view, the Longwood long barrow sits just across the valley. This is another substantial barrow, suggesting the valley was of some importance in #Neolithic times

3/7 It is interesting that the newly discovered barrow is only 300m from the Warren Farm long barrow, recently shown to be a massive 135m in length - see t.co/UMN3LGY14l

2/7 The cropmarks show the infilled flanking ditches of a long barrow. They are almost parallel, but taper slightly, and the barrow was probably about 35-45m in length. The LiDAR shows traces of a ploughed out mound.

8/9 If this monument really is so large, it is interesting to ask why it is located where it is. Circled on the map below, it is on the edge of only a sparse scatter of long barrows ...

7/9 It is so long, it can also be compared with bank barrows, which are extremely long parallel sided mounds. In this case, it is probably not sufficiently regular to be included in this class ...

6/9 Its form can also be compared with other large Hampshire long barrows ...

5/9 If this #Neolithic long barrow really is 135m, how does it compare with other Hampshire long barrows? The chart shows just how much longer it is, an incredible 25m more than the next longest ...

4/9 When the cropmark traces are overlaid onto the LiDAR, they perfectly flank the mound, appearing to confirm that the 'ridge' is actually an extension, or tail, to the mound ...
August 22, 2025 at 3:37 PM
3/9 However, recent imagery on Google Earth shows what appear to be two sections of ditch ...

2/9 The Warren Farm long barrow is 5km south-east of Winchester and was recorded by RCHME as 60m in length, located on a 'narrow ridge'. LiDAR plots suggested this 'narrow ridge' might actually be an extension of the mound, but this was hard to prove. ...

Hugh Davies (2002, Fig 12) provides a handy schematic including these small 'outer' ditches (A and A') in his book 'Roads in Roman Britain'. (4/4) #Archaeology

Ivan Margary (1973, 22) suggests such ditches mark out a 'road zone' for Roman roads, with the agger of the road built centrally between them. He describes two 'classes' of ditch separation, 84 feet and 62 feet. The Old Sarum example matches the former almost exactly (3/4)
August 14, 2025 at 8:46 PM
They also appear on aerial photographs, allowing the distance between the ditches to be measured - approximately 26m (85 feet). How did these ditches relate to the road? (2/4)

1/4 Traces of possible ditches flanking the Portway #Roman road at Old Sarum #Wiltshire currently showing as cropmarks. You can see the modern road in the background that follows the line of the Roman Road. #Archaeology

For #MapMonday, here is the fantastic Ordnance Survey 1932 Map of Neolithic Wessex in 3D. I've uploaded a copy of the model to #Sketchfab so anyone can zoom in and out, spin the map around etc: skfb.ly/pxySs. #Archaeology #OrdnanceSurvey #Neolithic #Wessex 1/2

Big fire at Old Sarum #Salisbury now

Here is a #Lidar map of the #Neolithic long barrows north-east of the village of Martin #Hampshire, up on Cranborne Chase. The insets are all at the same scale and allow a comparison of the extant mounds, which are diverse in shape and size. #Archaeology

There are some very 'long' #Neolithic long barrows on Cranborne Chase near Martin, #Hampshire. Buried ditches shown in magnetometer survey results, draped on #Lidar. #Archaeology #TombTuesday

5/5 Pentridge 26 not only shares a similar morphology to Wor Barrow. Each are intervisible across a chalk valley, and act as local horizon features when viewed from each other. Discussed in Gill 2021 'Shedding new light on the long barrows near the Dorset Cursus' Dorset DNHAS Proceedings 142.

4/5 The survey results for Pentridge 26 can be compared with cropmarks and the LiDAR representation of the ploughed out mound ...
January 31, 2025 at 5:28 PM
3/5 The survey of Pentridge 26 suggests it was built in a number of phases, similar to Wor Barrow and other Neolithic monuments, such as that at Barrow Hills in Oxfordshire ...
January 31, 2025 at 5:28 PM
2/5 The location of Pentridge 26 can be seen in the following Lidar plot, which shows it is adjacent to the Dorset Cursus, as well as near other long barrows, including Wor Barrow, another similar long barrow that was excavated by Pitt Rivers in the 19th Century ...

1/5 Just finished the report for a #geophysics survey of ploughed out barrow 'Pentridge 26'. Located next to the Dorset Cursus, it is scheduled as a bowl barrow, but the survey shows it is in fact a much earlier #Neolithic long barrow. Download from: avonvalleyarchsoc.wordpress.com/reports/ ...
