Nassau Hall, built in 1756, was the university's first permanent building at its current location. It served for a time as the seat of government of the United States and remains the university's administrative headquarters today. The surrounding part of the old campus grew in the 18th and 19th centuries with additional buildings in the colonial and neo-Gothic styles. It is compactly laid out, clearly structured, and forms the historic center of the university. Central academic and administrative activities still take place here today.

The Washington Crossing Bridge spans the Delaware River, connecting the historic Washington Crossing Parks in New Jersey and Pennsylvania. This narrow iron truss bridge, built in 1904, accommodates two lanes of traffic with a 3-ton weight limit and a 15 mph speed limit. It has a 3'6" wooden pedestrian walkway, and traffic signals at each end manage the flow of vehicles due to the bridge's narrowness. The Delaware River Joint Toll Bridge Commission has recently announced plans to replace the bridge to address safety and operational issues. The new design will feature wider lanes, shoulders, and a pedestrian path, aiming to improve traffic flow and safety while still respecting the area's historical significance.

A slight drop in the Delaware River creates a low waterfall shelf that is a popular spot for kayaking and fishing. A parking lot and lookout area can be found just off of the D&R trail. When water levels are high it is possible that the falls disappear under the surface, but you still get a great view of the river.
