A spa pool created by William Connolly at Castletown House rediscovered.

Thermal spa water, which has a constant temperature of twenty degrees Celsius was originally discovered during the construction of a section of the Royal Canal near Leixlip in the 1790s.

Curative spas were very much in vogue all over Europe at that time, and William Connolly, nephew of 'Speaker Connolly' of Castletown House, wished to develop the site into a fashionable classical thermal spa for wealthy Georgians. The plans never came to fruition, as William Connolly died in 1754.  

This remnant of Kildare Georgian heritage was rediscovered by the community in Leixlip in recent years, has been excavated, and the mineral rich waters have been diverted into a section of the restored baths.  

An Taisce, Bord Fáilte, the Irish Georgian Society and the Dublin Naturalists' Club, have all shown interest in the well and baths, and Kildare County Architect Niall Meagher believes that, 

The spa well should become a protected amenity under the county council's ownership.
