Between Circles 19 and 26 are the remains of several destroyed sites. Site 20 is a low mound with five boulders remaining. A few paces to the south is Site 21, a massive boulder that may have belonged to a circle. It is possible that it was the capstone of a dolmen, though at Carrowmore such stones are usually split in half.
Circle 22 is probably fairly complete, but it is hard to judge, as it lies partially buiried under quarry spoil. It looks to have had a large diameter. This monument would be well worth restoring. Circles 23, 24 and 25 are completely destroyed by the large quarry.No. 20. Situated about 20 paces south of 19 (dolmen-circle). This circle was of small diameter, and consisted of twelve stones, five of which had been recently removed." - Petrie.
No. 21. "Still further south" (dolmen-circle). "A few stones of this circle, with the table-stone of the cromleac, still remain." - Petrie.
No. 22. Situated south (or southeast) of 21; "6 paces from it;" "close to the road" (dolmen-circle). "This is a fine double circle, with a cromleac, partly ruined, in the interior. The diameter of the outer circle is 53 feet, and of the inner one 32 feet.
The stones in both are, as is most usual, placed quite close to each other. The number of stones in the outer circle is forty-five, but they appear to have been originally fifty-two (the same number as in 29), as places for seven are empty.
Within the cromleac an interment was found by Mr. Walker." - Petrie.
No. 23. Situated about fifteen paces to the south of 22 (dolmen-circle). "This circle is considerably injured, seventeen stones only remaining of it, although it originally consisted of thirty or thirty-two. The diameter is 36 feet. The stones of the cromleac remain, but are displaced, and human bones have been found within it." - Petrie.
No. 24. West of 23 (dolmen-circle). "There are 23 large stones, which evidently belonged to another circle now destroyed." - Petrie.
"They have been rolled to the bottom of the hill in clearing the land, and placed in a row." - Wood Martin.
No. 25. Situated 6 paces west of 23 (dolmen-circle). "Of this circle only 9 stones remain, and no cromleac. The diameter was 45 feet." - Petrie.
"The site is now entirely cleared." - Wood Martin.
