|Different types of nested enclosures|
|There are three main types of native farms:|
- TYPE A consists of irregular, mostly curved groupings. Vaguely oval-shaped forms may be seen, but these are rarely perfectly oval like at Drucat (Somme). Their funnel-shaped entrances are fairly characteristic, but not omnipresent.
This type is generally associated with a large number of pits, such as at Capelle-Fermont
- TYPE B is much more common.
It consists of two enclosures that are very different in shape: an internal closure (I), which is regular in shape with straight sides, and is generally rather compact. The second enclosure (II) is irregular, with a curved outline, and is most often very large. There are several examples of this. Sometimes the internal partitions are observable.
In several cases, Gallo-Roman foundations can be discerned in a type I enclosure. We can also find identical systems of type II nested enclosures surrounding certain small Gallo-Roman villas.
The two photographs of Blangy-Tronville (Somme) in the photo gallery on the next page are good illustrations of the need for a number of flyovers, as well as the caution that must be exercised when interpreting based on a single aerial view.
Just because a Gallo-Roman foundation does not appear in the photo doesn't mean
that it doesn't exist!
This is also indicative of the similarities that exist between a native farm and a Gallo-Roman villa; probably the one gave way to the other.
