Tri-States Monument

The Tri-States Monument is a granite marker in Port Jervis that marks the precise point where the borders of New Jersey, New York, and Pennsylvania meet. It sits near the confluence of the Delaware and Neversink rivers and features engraved state initials along with grooves that indicate the boundaries between the three states.

In 1882, surveyors installed this granite marker to replace an earlier copper bolt that had marked the meeting point of the three state boundaries. This upgrade ensured the border point remained permanently and clearly marked as surveying methods became more precise.

The monument attracts visitors from all three states who come to stand at the exact point where their borders meet. People often photograph themselves here to capture the experience of being in three places at once.

The site is easily accessible for visitors who want to see where the state lines converge near two rivers. It remains open year-round and allows for a quick visit to experience standing at the boundary intersection.

The monument was originally placed at a different location but was later moved to align with updated surveying results. This relocation shows how improved surveying techniques changed the precise definition of where state borders actually lay.
