Linda, at the moment they are undertaking 'archeological excavations', albeit with backhoes. So whatever you've seen will be pre-dating whatever!Some excavations were done years ago which were quite interesting, - they'd have to dig deep now, because they bulldozed much of the overburden when piling banks up the inside of the site's perimeter some years back, intending to keep out 'travellers', who posed a problem at the time.
