17 General Facts about Ireland

#1. There were never any snakes in Ireland

The tale of St. Patrick banishing snakes from the Emerald Isle is an age-old legend, but the fact is there have never been any snakes on the island of Ireland, due to being separated by Britain and the rest of Europe by water, they were never able to make it across, obviously. So what did St. Patrick chase out? Pagans.

#2. Around 78% of Irish people are Roman Catholic

While this is a significant decline from 84% in the 2011 census, the country still has one of the highest church attendances in Europe, with 88% of Irish citizens identifying as nominally Roman Catholic.

#3. There are more Irish outside Ireland than in

Ireland has a population of around 5 million, which is still almost four million less than the population before the Great Irish Famine of 1845-1852.

However, its been reported that almost 80 million people around the world have Irish passports – with up to half the population of Australia as well as some 40 million Americans claiming Irish heritage. The reasons behind such enormous emigrations is the famine and the search for better opportunities abroad, particularly in America in the 19th Century.

#4. Ireland is known as the Emerald Isle because of how green it is

Ireland from space

More than 30% of the population live in rural areas – higher than the EU average of 27%.

The flag of Ireland is a green, white and orange tricolour. The green symbolises the Gaelic tradition of Ireland, the orange represents the followers of William of Orange, and the white signifies the aspirations for peace between the two.

#6. The most popular sport in Ireland is Gaelic football

This is closely followed by Hurling, another ancient Gaelic sport. Both sports are native to Ireland.

#7. English is not the first language of Ireland

Although English is indeed the most widely spoken language in Ireland, with most claiming it as their first language, Irish is in fact the official language. It can be seen on all official government documents as well as public transport, signs, and public buildings. Despite Irish being taught as a subject in schools across Ireland, a lot of people still struggle to hold a simple conversation as gaelige.

#8. Ireland has its own version of the Olympics

One of the more unique facts about Ireland is that it has its own Olympics, known as the Tailteann Games which originated in the country around 1600 BC.

#10. Ireland was the Titanic’s last port of call

The Titanic was built in Belfast, Northern Ireland. While the ship officially left for America from Southampton, England, its last port of call was in Cobh, County Cork. While The Titanic Experience in Belfast is a popular visitor attraction, few people visit the small coastal town in Cork where you will find statues in memory of those who died, as well as a small Titanic Museum on what was once the old railway station.

#11. It took 15,000 Irishmen 3 years to build the Titanic in Belfast, Northern Ireland

Three million rivets held its massive hull together. The cost of a first-class ticket is estimated to have cost at least €89,000 ($106,000 ) in today’s currency.

#12. Ireland has one of the world’s youngest populations

This is due to the high birthrate, especially within the last 50 years.

#24. Being drunk in public is a criminal offence


Despite the common stereotype surrounding the Irish and their drinking habits, a law passed in 2009 made it illegal to be drunk in Ireland. The only day of the year when this law is slightly bent is, yep – you guessed it, St. Patricks Day, this is simply due to the fact that there aren’t enough police officers to monitor the million-plus tourists that pour onto the streets of Dublin on that day.

#25. The Shamrock is NOT the national symbol of Ireland
