Circles 5 and 6: destroyed monuments at Carrowmore
There are scant remains of Circles 5 and 6. These monuments seem to have been removed during land clearance around 1815. Circle 5 is clearly shown on Beranger's map of 1779, where he marks Circle 5 as a semi-circle of stones. The remaining portion of this ring were used to build a field wall some time before Petrie's visit in 1837. Petrie stayed with his younger friend Roger Walker, a landlord and antiquarian.
Walker showed Petrie the monuments at Carrowmore, many of which he had previously opened and cleared out. During his visit, Petrie questioned and interviewed the tenants on the land to find out how many more circles had been destroyed. He believed that many of the large circles to the south side of Carrowmore were destroyed around the same time, shortly before his visit.

The stones of Circle 5 are still clearly visible in the field wall close to the buried Pahntom Stones.The large split boulder, now standing upright may well have been the capstone.

No. 6 (1) (dolmen-circle). The situation of this is marked by a gravel-pit Northeast of VII.
"This circle and cromleac were destroyed about the year 1815 in raising gravel."
- Petrie.

IX. No. 6 (2) (dolmen-circle, between the gravel-pit and X).
"Several very large stones, which there can be but little doubt belonged to another circle."
- Petrie.
