In mid-1995, the North Western Health Board leased "The Show Field" at St Conal's Hospital to the local council so as "to provid[e] this very considerable community amenity to the people of Letterkenny" with the intention to develop a town park.

In 2008 Letterkenny Town Council were urged to carry out a review of the park's security following a public sex act and bouts of anti-social behaviour, bullying, and vandalism.

[8] A new Letterkenny Outdoor Gym (for which Healthy Ireland provided funding of €40,000) also came into use within the park's boundaries about this time; the groundwork had been begun earlier in the year, though its opening was announced then delayed on several occasions.

[8][9][10][11] A Garden of Remembrance opened in honour of the memory of members of the Gardaí and Army who have given their lives in service of the United Nations.

The luminarium is an inflatable environment, a participative sculpture made of translucent vinyl which has attracted nearly 2 million visitors in 34 countries around the world.
