Well, I find it amazing that within the city limits there are such prehistoric remains readily visitable...
Having checked on Archeologia Cambrensis turned out that the shown enclosure is thought to be medieval, which I find preposterous, but am no expert.
The view on photo 4 is of Cardiff in a roughly E direction, but the city centre is not visible as it is around the corner, literally.
Also that the village of Caerau nearby is the direct descendant of the Roman village, with a fort there, which I have not found yet; but going through the village itself the grid pattern is evident, and it "feels" old.....
more to come soon..... :O)
