Archaeology
A decorated stone which has been interpreted by some as the cult image of Crom Cruach was found at Killycluggin, County Cavan, in 1921 (Site number 93, Killycluggin townland, “Archaeological Inventory of County Cavan”, Patrick O’Donovan, 1995, p. 19). O'Kelly, however, refers to this image as Crom Dubh. Roughly dome-shaped and covered in Iron Age La Tène designs, it was discovered broken in several pieces and partly buried close to a Bronze Age stone circle, inside which it probably once stood. The site has several associations with St. Patrick. Nearby is Tobar Padraig (St. Patrick's Well), and Kilnavert Church, which is said to have been founded by the saint. Kilnavert was originally called Fossa Slécht or Rath Slécht, from which the wider Magh Slécht area was named.
Although now much damaged, the stone can be reconstructed from the different surviving pieces. At the base of the stone there were four rectangular adjoining panels measuring 90 cm each in width giving a circumference of 3m 60 cm when it was first carved. The height of each panel was about 75 cm. When excavated and placed upright on its flat base, it was found to lean obliquely to the left from the vertical, perhaps explaining the name Crom, "bent, crooked". The Killycluggin Stone, as it is known, is now in the Cavan County Museum, while a replica stands near the road about 300 metres from the original site.
The 14th century Book of McGovern, written in Magh Slécht, contains a poem which states that Crom was situated at Kilnavert beside the road and that the local women used to tremble in fear as they passed by. There is still a local tradition in the area that the Killycluggin stone is the Crom stone.
There is another standing stone identified with Crom Crúaich in Drumcoo townland, County Fermanagh. A nearby street is named Crom Crúaich Way after it. It has the figure of a man walking engraved on it which either represents Saint Patrick or a druid, depending on when it was engraved.
