Ireland has a unique, and beautiful national symbol and it’s the harp. It is the only country in the world that uses a musical instrument as its symbol. The traditional instrument is featured on Irish coins, the Presidential Seal, the Irish passport and the Irish coat of arms. Scholars have found that the Irish harp’s popularity with the Irish people dates back to the 1500’s. Ireland’s national emblem is actually based on the Brian Boru Harp. Irish legend says Brian Boru played the harp the night before the Battle of Clontarf.
