The "Rotunda, Rutland square" is a group of connected buildings on Rutland (now Parnell) Square, just beyond the north end of Upper Sackville (now O'Connell) Street where it leads into Cavendish Row. The complex housed the oldest maternity hospital in Ireland, and possibly the world, in addition to theaters for arts and entertainment, and rooms for hosting social and fundraising events.
