Characterising the distribution
A new review
An estimated total
Aerial photographs of Thanet's fertile agricultural lands have helped to reveal the hidden history of the Isle, demonstrating the rich archaeological legacy created by our ancestors.
These aerial photographs (APs) have shown that Thanet has a large number of ring-ditch monuments, the vast majority representing Bronze Age roundbarrows. The ring-ditches appear in single, double and triple-concentric ring forms; the multiple rings resulting from the re-use and refurbishment of earlier monuments.
|Several of the ring-ditch cropmarks have
been tested by excavation in
recent years and these add to our knowledge of some that were excavated
before the aerial photographic resource was available.
While the best efforts have always been made to identify and plot the ring-ditch monuments from (frequently oblique) APs, it is not possible to present a single, unarguable figure or plan of the total number of these monuments present in the landscape.
Cropmarks are dependant on the underlying soil type, the ground cover or vegetation, agriculture and the changing seasons.

may reveal different cropmarks at
different times over many years.
What we can say is that the data revealed in these ongoing studies represents the minimum baseline figures for Thanet's roundbarrows - an impressive statistic in itself!

|The numbers game
The RCHME survey of Kent (1989) reported the following cropmark sites:
Concentric BA ring-ditches: 50
Single BA ring-ditches with internal features: 73
Single BA ring-ditches without internal features: 518
EMED* (ie Saxon) ring ditches with internal features: 30
EMED* (ie Saxon) ring ditches with internal features: 169
* in this report it was decided that ring-ditches less than 10m in diameter were provisionally dated as Early Medieval (ie. Saxon), while diameters of 10-30m were dated as Bronze Age.
|Subsequently Dr. David Perkins
that 739 ring-ditch cropmarks were known from Kent; the vast majority
of which were likely to represent
roundbarrows. Dividing these along geographical lines, he reported that:
356 (48.2%) of these fall within East Kent's 'Sutton wedge'. This is an area of 234 square km which shows a high concentration of archaeological sites and has the village of Sutton at its centre.
315 (42.6%) appear in Thanet, contained within an area of only approximately 64 square km.
68 (9.2%) can be seen in the rest of Kent; mostly on high ground west of the Medway.

Not all soils or types of ground-cover are conducive to the formation and identification of cropmarks of course and much may remain concealed or have been destroyed by subsequent development.
Peter Clark (pers comm.) noted that Canterbury Trust's excavations on the Monkton-Minster A253 road scheme (1993) revealed the presence of more roundbarrow monuments than had been indicated by the cropmark data (despite the fact that the underlying chalk geology usually provides the best circumstances for cropmark formation).
Dr. David Perkins' comprehensive study (1999) reviewed aerial photographs from several different sources and this revealed more ring-ditches than had been seen in a published RCHME survey. In comparing Perkins' plan of Thanet's ring-ditch cropmarks with the RCHME plots it can been seen that within some 500 square metre locations he had discovered up to six extra ring-ditch cropmarks.
This all helps to illustrate that the statistics concerning Thanet's roundbarrow archaeology must be taken in context and viewed as minimum estimates only.
