Foel Drygarn fortified settlement

Here is another fabulous image from the Bing satellite coverage.  It shows the Foel Drygarn hillfort / fortified settlement at the eastern end off the Mynydd Preseli upland ridge.

You can see very clearly the three Bronze age burial mounds, the main Iron Age (?) fortified site enclosed by an embankment (with the pitted surface showing where the huts were located), the subsidiary embanked area to the north (with more hut circles), and the animal enclosure (?) on the NW flank of the inhabited area. 

"Foel Drygarn" means "the bare hill with three cairns".
