State Line Boundary Marker
The State Line Boundary Marker is thought to be the oldest
surviving monument in the city of Chicago. It sits on the northern
political boundary between the states of Indiana and illinois. A
similar marker at the southern end of the boundary on the banks of the
Wabash River no longer exists. It is estimated that the marker was
placed in 1833. Due to problems with vandalism, the marker was moved
north along the state boundary and it now sits next to the guarded entrance
to the Stateline Generating Station.
