Nassau Hall (or Old Nassau) is the oldest building at Princeton and for a long time served as its main academic and residential building. At the time it was built in 1756, Nassau Hall was the largest building in colonial New Jersey and the largest academic building in all the American colonies. From June 30 to November 4, 1783, Princeton was the provisional capital of the United States and Nassau Hall served as its seat of government. The Congress of the Confederation met in the building's library on the second floor. Here Congress congratulated George Washington on his successful termination of the war, received the news of the signing of the definitive treaty of peace with Great Britain, and welcomed the first foreign minister—from the Netherlands—accredited to the United States. Starting in 1869 each graduation class adds a new sprig of ivy to grow up the walls of the building.
