Sites 46, 46a, 46b and 47
This monument is a ringfort with a diameter of 36 meters, and is not related to the megalithic monuments, belonging to a much later period. Ringforts were generally constructed from the early Christian to Medieval eras. They were mostly homes for farmers. 46a is probably a small hut foundation, which may date to the stone age. I can't find any reference to say what 46b might have been.
Petrie records that an unbroken chain of at least 6 circles were destroyed here around 1793. There are many stray and erratic boulders, and some 30 to 40 have been gathered aound the south side of a water hole here. Certainly, when you look across the fence to the east, the field looks completely cleared. The photo above shows the spread of boulders to the west.
No. 46Situated in the next field to LVII, to the west, and "close to the ditch which cuts off a portion of it." - Petrie. It is a few paces to the northwest of LVII (caltragh?). "This circle appears rather to have been a cashel or fort than a place of interment. The diameter is about 120 feet, and the wall 10 feet in thickness. It is composed of enormous-sized stones mixed with earth, and has a ditch and bank surrounding it. It has also two smaller walls within it, and extending across it in parallel right lines, as see the plan." - Petrie. "This curious monument appears to have been originally rudely circular...... The circumvallation consists of an earthen rampart mixed with stones, and about 10 feet in thickness. In the interior are two smaller banks extending across it in parallel lines. None of the enormous-sized stones which formerly composed the rampart now remain; but two boulders on either side of the gap in the south arc of the circle may perhaps mark the jambs of a rude entrance." - Wood-Martin. Circular earthworks divided by a bank traversing their interior area are known to German archaeologists. See drawing of the "Schlossberg" near Witzen in the Neues Lausitzishes Mag., vol. lvii., pl. facing page 466.
No. 46 (a)
Near No. 46 (dolmen-circle). This is not noticed by Petrie. "It is a very diminutive circle, 10 feet in diameter, hollow in the centre, and surrounded by thin flags, ten in number. An excavation was made, but without result." - Wood-Martin. Col. Wood-Martin compares it to a circle in Achill (co. Mayo').
No. 46 (b).
About 150 paces to the south of No. 46 (caltragh?). "A very similar structure to No. 46, not hitherto noticed" (and therefore not in Petrie's list). In common with No. 46, Col. Wood-Martin regards this as a sepulchral monument. It is not within the range of his map, but it makes the sixth monument of the class included in the Carrowmore group. Rude Stone Monuments, p. 66.
No. 47. Situated immediately to the west of No. 46 (dolmen-circle, and at least 6 others). "This circle is in part destroyed. About twenty stones remain. In the same field to the W. there are a vast number of large stones (the boundary wall is in great part composed of similar stones); but it is impossible to trace, with any certainty, a circular arrangement among them. It is certain, however, that within the memory of the present inhabitants of the townland, the chain of circles was carried on without interruption through the great field immediately to the north. They were destroyed by Mr. Walshe, who got a lease of the land from Lord Erne in 1793, to clear the ground. The peasants who were employed in their destruction remember six or more of them distinctly, and the stones of which they were composed still remain partly in pits within the field, and partly in the surrounding walls. In all these circles bones were found beneath the cromleacs. Towards the north of the field the series is again resumed." - Petrie.
