That seems to be a significant difference between
walled and ditched enclosures in Portugal.

Naturally, as argued before (for instance here), no
building is performed in an insignificant space. Everything built is in dialogue
with a local landscape, with its meanings, visibilities, resources,
particularities. And all of those previous conditions are, in one way or
another, incorporated in the building.
But when we compare walled and ditched enclosures we
can observe that the former tend to present a great variety of forms of
adaptation and incorporation of previous elements of the landscape, while the
ditched enclosures mainly reflect a dialogue with topography, geology and
visibility conditions.
Rocks, tors
or cliffs, are usually incorporated as part of the structures that enclose.
Although in other parts of Europe we can see that also in ditched enclosures
(like the French “enceinte à éperon”), so far those solutions were not identified in Portuguese ditched
enclosures.

In terms of the architectonic features, walled
enclosures seem to use the available natural conditions in a different
way. Perhaps one of the reasons is that
the design, the layout, was less significant than the ones presented by ditched
enclosures and answered to different goals.
