Megalithic Mound or Natural Glacial Deposit?

I've often wondered about this area of raised ground and whether it's a megalithic feature. The ground rises gently on all sides, but the high ground isn't overly symmetric like other man-made megalithic sites in the landscape. It doesn't appear in any archaeological records. As kids, when we were looking for the legendary tunnel that ran from New Abbey to the Valley Park, I remember investigating a hole in the slope of the mound, lined with stones. Maybe it was the remains of a well? Does anyone remember this?

.....my archaeological discoveries from the garden. Found while digging and doing construction work over the last few decades. Probably nineteenth century stuff. My theory is that rubble from the demolition of the Carlow Stables was spread out to level the ground during construction of the Nicholastown housing estate and that's where some of these fragments may have came from. During the era when a Bianconi coach service ran from Dublin to Cork, via Clonmel, horses were replaced at intervals along the way. The Carlow Stables in Kilcullen was one of the relay sites. The building was located just before the first turn into the estate, heading south. Some of the fragments I found were rough pottery with glaze, so these could be pre-nineteenth century and not manufactured in moulds or by machine. One piece has shallow grooves, possibly made by finger marks when the pottery was turned on a wheel. The top of a flagon came from outside the wall of my house, dug up when the council was fixing a broken water main almost 20 years ago. It's embossed with the text "Price Bristol". That grass bank outside the house probably contains a treasure trove of items, lost and discarded over the centuries since the road and the trail which probably preceded it has been in existence. I also found a piece of red brick, three feet under the ground, when I was digging a soakaway in the front lawn, but there were no houses in the area before the estate was built. The triangular tile-like objects were found when I was digging the foundations for my gate piers a few years ago. Not sure what they are.
