The hospital, which was initially established as a
tuberculosis sanitarium, was designed by Norman White and constructed by
Sisk Builders. It was named in memory of the
Irish republican leader,
James Connolly, and officially opened as the James Connolly Memorial Hospital in 1955. The government allocated 6.8 acres on the Abbotstown lands at Blanchardstown for the building of a
hospice under the care of the
Daughters of Charity. This was a
sister site to their hospice in
Raheny. Construction works were completed in April 2011. A satellite facility for the
New Children's Hospital, providing outpatient facilities and an urgent care centre opened in summer 2019. ==Teaching==
