The twentieth century in Ardee was saluted early on by the first Brass Band. I was not able to discover the exact year but am reliably informed that it was in the first decade.

In 1911 the first Golf we know of hereabouts was played at Baltrasna and in 1914 the Ardee Electric Light Company started operations. At first steam was used in generating on the premises now enclosing Dolans Grain Store but in 1926 John McKeever and his company moved across to Moore Hall (where McGees grain store now is) and began using a 60 Horse power National Diesel Engine. (About 1932 a 100 H.P. two-cylinder engine was installed). The Ardee Bread Company began baking in 1908.

In 1916 the Lawn Tennis Club was set up and courts were laid down on the Town Parks by Eddie Carrager of Cardistown, though there was a tennis club in the 19th century in Charlestown. In 1922 the Golf Club also moved into Town Parks and the year also saw the end of the old Hospital/Workhouse. Ardee House became St. Joseph's Hospital in the care of the Sisters of Mercy. The old hospital was made suitable to house a new Technical School.
