Tri-State Marker

The Delaware–Maryland–Pennsylvania Tri-State Point is the meeting of the northwestern corner of Delaware, the northeastern corner of Maryland, and the southern edge of Pennsylvania. A wooden marker was placed in 1765, by Charles Mason and Jeremiah Dixon, and was replaced with a stone marker in 1849.

The tripoint site contributes to the Delaware Boundary Markers historic district, listed on the National Register of Historic Places in 1975. A trail to the marker was made in 2014–2015.
