Castledermot is best explored through its stone monuments and monastic remains. The round tower, high crosses and church ruins define the town's historic focus. Important for planning: the round tower can only be viewed from outside; entry to the interior is not permitted. Allow up to an hour for the site with its round tower, high cross and St. David's Graveyard. Check the latest access information before your trip. The ground-level entrance does not change the restriction on entering the interior.
The Round Tower and Early Monastic Settlement
Castledermot's round tower is a National Monument in state care. It dates from the 10th century, is approximately 20 metres high and has five levels. The granite fieldstones give its masonry a pebbled appearance, while the battlements look medieval. The tower stands north of the main church. Its silhouette helps visitors identify St. James's Church in the landscape and also makes it a landmark in the historic town.
The monastic settlement was founded by the 9th century at the latest and is associated with St. Diarmuid, who died in 825. Its features include grave slabs, cross-slabs, stones inscribed with crosses, high crosses, architectural fragments, the round tower, a hogback tomb and the parish church of St. James. The site is also the burial place of Cormac mac Cuilennáin, Bishop and King of Munster, who died in 938. The North Cross stands in the graveyard: a tall, 10th-century granite ringed cross.
St. James's Church and Its Surroundings
St. James's Church forms the historic core of Castledermot and continues a long-standing ecclesiastical presence at the site. Its grounds include the remains of a 12th-century church and a 10th-century round tower, both of considerable archaeological significance. The striking church building stands on Church Lane and can be viewed from Abbey Street through the western avenue. Castledermot's hogback stone is unique in Ireland; it is one of the distinctive funerary monuments of the monastic settlement.
Franciscan Friary and Monastic Trail
Castledermot Franciscan Friary was built around 1247 on the site of an older monastery founded by St. Diarmuid. It was attacked and plundered during the Bruce invasion of 1315 to 1318, then rebuilt. Today, only the ruined church remains of the once important settlement. It was built of regularly coursed granite, with granite blocks accentuating the corners of the building. Several lancet windows lit the transepts and chancel, some with tracery in varied linear patterns.
The Kildare Monastic Trail leads to Castledermot Monastery, where visitors can discover high crosses, a round tower and a Scandinavian-influenced Viking hogback tomb. At Castledermot Friary, you can walk the trail through the remains of the Franciscan friary that served the medieval town. The earlier monastic settlement and the later Franciscan site thus stand alongside one another as distinct historical points of interest.
Another Perspective in County Kildare
A separate option for exploring the landscape of County Kildare is Donadea Forest Park. The Lake Walk is 0.8 km long, takes about 30 minutes and is accessible to everyone. There are also three permanent orienteering courses: a short one of 1.8 km, a medium one of 3.4 km and a long one of 4.6 km. These routes offer a different kind of experience from Castledermot's monuments: the Lake Walk combines a short distance with an approximate duration, while the orienteering courses are graded by length.
