Diseart Chiaráin, the hermitage of Ciarán
Castlekeeran and the crosses in the river
A kilometre south of the village, on the south bank of the Leinster Blackwater, a walled graveyard holds three weathered sandstone high crosses and an ogham stone - and a fourth cross stands out in the river itself. The site was the Diseart Chiaráin, the hermitage of Ciarán the Pious of Bealach-duin, a monk associated with Kells who died on 14 June 770 (not the Ciarán who founded Clonmacnoise). The crosses are termon crosses, from the Irish tearmann, a boundary, marking the sanctuary at the heart of the monastery. The Annals record the place plundered by the Danes in 949 and raided by Diarmait Mac Murchada in 1170. The ogham reads COVAGNI MAQI MUCOI LUGUNI - Cuana, son of the people of Lugh. It is a National Monument, publicly accessible, free, and on most days completely deserted. Bring boots; the field can be wet.
Carnaross Livestock Mart
The first virtual mart in Ireland
For a village this size, the mart is a serious operation and the reason the place exists as a meeting point at all. Sale days fill the village with farmers, jeeps and trailers, and the pub takes the overflow. Its claim to a footnote in history: during the COVID-19 restrictions in 2020, when farmers could not gather in a sale ring, Carnaross ran what is recorded as the first virtual mart in Ireland - the cattle in the ring, the bidding online. A small north Meath mart, briefly, leading the country.
A 19th-century church made of sheet metal
The Iron Church
On the R147 through the village stands one of the odder buildings in the area - a former Church of Ireland church built in the 19th century out of corrugated sheet metal. So-called "tin tabernacles" were a Victorian way of throwing up a cheap, quick place of worship. This one fell out of use as the parish church and was later bought and used as an independent evangelical chapel. It is a private building and not a visitor attraction, but it is a genuine curiosity if you are passing through.
