James FitzGerald, 1st Duke of Leinster

Leinster House in County Dublin became the final resting place of James FitzGerald, 1st Duke of Leinster, after King George III raised his ancient Kildare line to the peerage's highest rank in 1766. The building therefore holds more than stone and chamber; it holds the moment a medieval Irish family became the premier ducal house in Ireland. To walk its rooms is to pass through the life of the man whose death helped shape the house's identity.
