7 Wonders of Ireland

Ireland has lots of ingenious places, but some of them are really special, and we reckon there are at least 7 ingenious wonders that are truly world class.  We’ve outlined our 7 Wonders below — they are all national treasures, and we hope this will encourage you to visit some of them, maybe even all seven!

Birr Telescope Ingenious Ireland Atlas

The great telescope at Birr, the world’s biggest for 70 years

Our chosen wonders include a great scientific discovery, several feats of engineering, and some amazing fossils and rock formations.

Seven Wonders of Ireland

In what you could say is ‘order of appearance’…

One of the World's oldest fossil trackway

Valentia Island’s fossil trackway

Amazing fossil footprints, among the oldest in the world, at Valentia Island, Co Kerry. These were made 385 million years by a creature resembling a salamander as it walked across some mud, and they have been preserved in the rock ever since.  Absolutely wonderful!

The Giant’s Causeway, Co Antrim: the polygons of rock are so perfect, people once thought they were artificial.  Actually, they formed when a vast lake of molten lava cooled slowly, 60 million years ago. The region also has ancient volcanoes, caves, fossils and rare minerals. Lots to see in this UNESCO world heritage site!

The wonderful, unmistakable Burren in Co Clare

The wonderful, unmistakable Burren in Co Clare

The Burren, Co Clare:  blessed with riches, this is a strange, rocky limestone landscape, with tremendous ecological diversity; amazing caves; and the flowers are justly world-famous, including 23 species of orchid. Best time to visit is May.

The world’s oldest astronomical observatory — Newgrange, Co Meath: this feat of precision engineering pinpoints the Winter Solstice, the turning point of the solar year, and it was built 1,000 years before Stonehenge,  by Neolithic people who had neither metal tools nor the wheel.

Eureka! A great scientific discovery, at Broome Bridge, Dublin:  On 16th October 1843, a revolutionary new type of algebra was invented here by Ireland’s greatest scientist, Sir William Rowan Hamilton, as he walked by the Royal Canal.  You could say that his algebra helped to land a man on the Moon, because it is used to control spacecraft and in 3D games.   A plaque marks the spot, and for scientists this is a place of pilgrimage!

The Hubble telescope of the Victorian Age, Birr Castle, Co Offaly.  The world’s biggest telescope was built in 1845, by William Parsons, third Earl of Rosse, and it could see further into space than ever before. With it,  Parsons discovered the Whirlpool Nebula, and other nebulae.   All built with local labour,  it was the world’s largest telescope until 1917.  Now restored to working order – visit, and see what you can see!

A wondering of the engineering world: the elegant Boyne Viaduct, still in use.


1855: a wonder of the engineering world, Boyne Viaduct, Drogheda, Co Louth: This elegant railway bridge on the Dublin-Belfast railway line,  was a wonder of the engineering world when it opened in 1855. To minimise the weight, it was made from a lattice of wrought iron girders, and was the longest of its kind of the world then, at 155 metres. And it’s still in use!
