In 2017, a new crest was created for Eureka, representing the many aspects of the school. The crown at the top, originally found on the shield of the Mercy Order, which established Eureka in 1956, is symbolic of Our Blessed Lady as our Queen. The open book signifies teaching and learning; it simultaneously provides a reference to the famous Book of Kells, which was completed in the local Columban monastery, itself a centre of learning in the early Christian period in Ireland.
