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.
