This tomb is classified as a portal tomb in the Carlow Inventory and on first sight you have to agree. A large capstone rests on two projecting portal stones with a full height doorstone in between - one wall of the chamber lies prostrate below the capstone.

However, closer inspection raises several issues. The portal stones are very low, just 1.2m, and the chamber would have been the same height. In front of the 'portal' there are definite signs of a courtyard and bits of the kerb. Walking to the rear of the tomb there are several slabs set across the line if the tomb in line with the chamber - perhaps indicating a gallery?

To me this just seems like one big hodge-podge of styles and really should be investigated properly. I'm sure that it would provide more questions than it answers though.
