The monastery of Clonmacnoise was our last stop before heading back to Dublin. It was founded in 546 by a young man named Ciarán, on the shores of the River Shannon. It’s strategic location helped it become a major center of religion, learning, craftsmanship and trade. By the 9th century, it was the most famous in Ireland, visited by scholars from all over Europe. Today, visitors can see three high crosses, a cathedral, seven churches and two round towers.
