The region is given a common character by its extensive Norman Heritage. This is reflected in the neat stone villages and numerous castle ruins of Celt and Norman origin.
The area also boasts its number of Neolithic sites, one of them being a perfectly preserved dolmen. A dolmen is a Celtic tomb made out of three or four gigantic stones, seven or eight feet high, forming a circumference of twelve - fourteen feet. This dolmen is on the outskirts of Carlow, a prominent township upstream on the River Barrow.
