Just discovered this website - seems like a 'good thing', congrats to organisers.
I had cause to visit/investigate Caerau hillfort 10 years or so age, when a member of Cardiff City Farm Trust - site was suggested as a possible alternative to our then site.
The following remarks are from my memory of a phone conversation with my archaeology consultant at the time - taken from his reference books.
The hillfort dates to pre-Roman Iron Age, is multi-vallate - ie more than 1 bank-and-ditch. These surround the entire open space, are only visible if you go to the edge & look down into the woods.
The small ringwork near the Church is a presumed 'Dark Age' re-occupation of the site in post-Roman period.
'Lumps and bumps' near the centre of the open space on the hilltop are remains of an abandoned Mediaeval village, linked to the Church, which was ruinous, vandalised when I visited c2000.
Hillfort possibly occupied by a local aristocratic family, who moved to Ely villa in Roman period, then back to the fort in post-Roman?
Needless to say, the site was rejected as a possible alt City Farm site!
I'll try & get up there, take some photos when the weather picks up a bit.
Something is not right. This message is just to keep things from messing up down the road
