This was the site of the Viking assembly mound or Thingmote, which survived here, until removed in 1685 to be used as infill on Nassau Street to prevent flooding. Named after Sir Thomas Howard, Earl of Suffolk, it was the site of the family home of the Earls of Kildare until James Fitzgerald built Leinster House.
