Clonmacnoise Monastic Site:  Top Reasons to Visit This Fascinating Irish Landmark

You'll find the Clonmacnoise monastic site on the banks of the River Shannon, in County Offaly. The ruins of a cathedral that was built in the 6th century now stands on the site, and for hundreds of years it was the most important religious landmark in Ireland.

The site is made up of several unique structures as well as a modern church.  It is a historic destination, offering an authentic sense of the history of Ireland.

To get to Clonmacnoise by car, you can take the M6 East from Galway or the M6 West from Dublin. Either way, it is a lovely journey across Irish countryside and won't take longer than 90 minutes.  

There's also a far less common way to get there: by boat! Since the landmark is right next to the River Shannon, some visitors arrive by boat for a unique way to experience the monastery.

Things to Know About the Clonmacnoise Monastic Site

Here are some fun facts about this amazing Irish landmark.  Hopefully they will entice you to pay a visit in person!  But if that is not possible, you can always use them to impress your friends with your knowledge of one of the most-visited attractions in Ireland.

  3. Many people mistakenly believe that the location is just one church. In reality, it's made up of one cathedral, seven churches, three original high crosses and two round towers. 
  4. The cathedral is the largest structure at the site, and it dates back to the 9th century. It is also where countless Irish kings and members of various royal families were buried. You can tour the graveyard to this day.
  5. The site was destroyed and looted by the English garrison from Athlone in 1552.
  6. As you walk the site today, you might be drawn to the beautiful Cross of the Scriptures (also called the South Cross), which stands at more than 12 feet tall. However, the one outside is actually a replica! The real one can be found inside at the Visitor's Centre.
  7. Near the Chapel of Clonfinlough, you'll see a handful of large limestone boulders. Look closer to spot the Horseman's Stone, which boasts a number of carvings that are believed to depict aspects of ancient Gaelic inaugurations.
