Princeton is best known for Princeton University, a college that was established in 1756, But there’s more to this town of 29,000 people than that. The town serves as the governor’s official residence, Drumthwacket, even though the state capital is in Trenton. Home to several Fortune 500 companies, Princeton offers numerous tourist attractions, including the house where Albert Einstein lived and the Washington Oak, so named because the tree was alive in 1787 when the U.S. Constitution was signed. Hoagie fans will want to visit Hoagie Heaven, a notable Princeton eatery famous for its sub sandwiches.
