Princeton — the campus and the town
Princeton University's main campus is one of the great pieces of American collegiate Gothic architecture, built largely between 1895 and 1930 in grey New Jersey bluestone and Princeton brownstone. The Blair Arch, the Nassau Hall front (built 1756, briefly the capital of the United States) and the tower of East Pyne are the buildings everyone photographs.
The campus is open to walk, free, every day. The Princeton University Art Museum holds around 100,000 works and admission is free — it is one of the best small museums in the country and almost nobody plans for it.
Then there is the town itself: Nassau Street for bookshops and coffee, the Bainbridge House and Morven Museum for history, and the former site of the Institute for Advanced Study connection to Einstein just outside the town centre.
