According to the official website of the Houses of the Oireachtas [the Republic of Ireland's Parliament]:
The designer of Leinster House [the seat of Ireland's Parliament] was the architect Richard Cassels, who was born in Hesse-Cassel in Germany about 1690. The design is characteristic of buildings of the period in Ireland and England. It has been claimed that it formed a model for the design of the White House, the residence of the President of the United States.
