Together with a brand-new ride named “The Celtic Dreamer,” the family and thrill coasters “Na Fianna Force” and “The Quest” comprise a brand-new 6.5-acre area of the park called "Tír Na nÓg," which is decorated with items made by nearby blacksmiths in the Boyne Valley.

Sixty-five global rollercoaster aficionados will try out the new coasters. Raymond Coyle, the park's subsequent creator, initiated the seven-year-long undertaking.

Charles Coyle, his son, and the current managing director of Emerald Park said the project was a landmark in theme park attractions and evidence of his father's lasting influence.

600 seasonal workers and 150 full-time employees work at Emerald Park in County Meath, which opened 14 years ago.

The Dutch manufacturer Vekoma, a significant supplier to The Walt Disney Company, created and constructed the coasters.

The tallest of the two new coasters, “Na Fianna Force,” is a 32-meter tall, suspended thrill coaster that can reach speeds of up to 90 km/h.

There are five inversions during the 750-meter ride that turn the rider inside out.

It is entwined with “The Quest” coaster, which is referred to as a “family boomerang rollercoaster” with a top speed of 60 km/h and a maximum height of 25 metres.

According to Charles Coyle, Managing Director of Emerald Park, this is Ireland's biggest tourism investment in at least five years.

“A huge, proud, and exciting moment has arrived with the investment of €22 million, marking the culmination of seven years of hard work. It's truly exceptional; nothing else in Europe compares.”

His father Raymond Coyle, the park's creator, initiated the initiative.
