Clonmacnoise

The monastery complex contains three high crosses, a cathedral, seven churches, and two round towers along the River Shannon near Shannonbridge.

Saint Ciaran established this religious center in 545 AD, constructing the first church with support from Prince Diarmuid, future High King of Ireland.

The monastery developed into a major center of learning, producing significant manuscripts including the Annals of Tighernach and Book of the Dun Cow.

The site maintains a visitor center displaying the Cross of the Scriptures and operates daily from 10:00 AM with admission fees ranging from 4 to 20 euros.

Despite experiencing 13 fires and 40 attacks between the 8th and 12th centuries, the monks rebuilt the monastery each time until 1552.
