Taking an hour to sing Greece has the world’s longest National Anthem at 158 verses long.

National Anthems represent a country's history, traditions, and identity - and it seems that Greece in particular has a lot to sing about.

Written by poet Dionysios Solomos in 1823 "Hymn to Liberty" or "Hymn to Freedom" depicts the hardships of the Greek people which they suffered from getting liberty from the Ottoman Empire.
