Irish grid reference N0099 3066. The monastic site of Clonmacnois or (Cluain Mhic Nois) meaning ‘the fields of the hogs of Nos’, stands within a walled monastic enclosure beside the banks of the River Shannon near Shannonbridge, Co. Offaly, Southern Ireland. It dates from 545 AD when St Ciaran (Kieran) 512-545, son of a chariot-maker from Rathcrogan, Co. Roscommon (Connaught), founded a great monastic establishment here, surrounded on the landward side by boggy land. There are three 9th century crosses, two round towers (one of which is still intact), upto 200 grave-slabs from the 8th-12th centuries, the ruins of eight roofless churches and also St Ciaran’s Cathedral, and many other interesting antiquities. Clonmacnois was once referred to as ‘a monastic city’ that originally had 105 monastic buildings, before the Vikings and, later the Normans came here in 1179 and, very sadly, destroyed many of them. In 1552-3 the site and it’s remaining buildings were badly damaged by the terrible atrocities following the Dissolution of the Monasteries, ’caused by’ the “English”. Clonmacnois lies just north of the R444 ‘Back Road’ between Moate and Shannonbridge, while the town of Athlone is 4 miles to the north on the M6/R446 roads.

Perhaps one of the finest and best preserved of the the high crosses (now partially restored) is that called ‘The Cross of the Scriptures’ (the Western Cross), dating from the early 9th century AD, near the west door of the cathedral. It stands at 4 metres (13) feet high and is made of sandstone; the front face shows scenes from the Life of Christ and other biblical scenes. The bottom panel (front) shows King Dermaid, son of Fergus, or of Aed? of the southern Ui Neill clan, helping St Ciaran the disciple of St Finnian of Clonard to build the first section of his monastery in AD 545 – with what could be a tree in between them? At the base of the cross there are scenes showing horses pulling a cart and, warriors riding on horses. An inscription recalls ‘a prayer for Colman who made this cross for King Flan’. The other two 9th century scultured high crosses – ‘the North Cross’ is badly damaged and the South Cross beside Temple Dowling is also quite damaged, but both still very rich in Celtic-style carvings.

One of the two round-towers stands to it’s original height of 17 metres and was used as a bell-tower for Temple Finghin (or St Finghin’s church), while the other, O’Rourke’s Tower, is damaged at the top, but is still some 20 metres high. Of the remaining churches The Nuns’ Church is perhaps the best. This dates from 1167 and is Irish-Romanesque in style; the carved chancel arch has beautiful geometric design-work; also the ruined St Ciaran’s Cathedral, which replaced an earlier 9th century cathedral, probably dates from the 13th or maybe 14th century, and has some beautiful carved figures of saints above the north doorway; the west doorway dates from 1200. The collection of 200 grave-stones inscribed with crosses and inscriptions in prayer-form are now housed in the visitor centre at the site, and there are another 500 smaller stones, some very fragmented. One stone, in particular, is round-shaped with a hole in the centre and a large incised-lettered inscription to the memory of SECHNASACH, an abbot who died in 928 AD; and another grave-slab with an elaborate Latin cross has an inscription in prayer-format to the memory of MAELFINNIA, an abbot of Clonmacnois who died in 921 AD. These stones would have marked the graves of former abbots of the 7th-9th centuries AD and, also a number of high kings of Mide, Brefni, Tara and Connacht. There are also three richly carved cross-shafts with Celtic ornamentation, but they are without their cross-heads.

St Ciaran, however, only lived for another seven months after the foundation of his monastery, dying at the age of thirty-three in 545 AD, or possibly 549 AD of yellow fever, according to some historians in the field of Irish monasticism. But undoubtedly this is one of Ireland’s “greatest monastic centres”, with much still remaining from the Early Christian period, although many of it’s monastic buildings are now in a somewhat ruinous state. Clonmacnois was regarded as ‘A Cradle of Celtic Christianity’ for 600 years. A hoard of Hiberno-Norse coins, dating from the late 11th century, was dug up close to the site in 1979 by a group of school children, and a number of other monastic antiquities including implements, bones and an ornamental twisted gold rod and copper-alloy ring, thought to be Hiberno-Norse. To the west of the monastic site and just north of St Ciaran’s National School, are the earthworks and walls of a Norman castle. The famous Clonmacnois crozier is now displayed in the National Museum of Ireland in Kildare Street, Dublin.
