In the summer and fall of 1988 Kansas Historic Society archeologists excavated at Constitution Hall in Lecompton, trying to trace the building's construction history prior to renovation. Shown in these photographs are an excavation unit with many artifacts exposed, a turn of the century sidewalk exposed, archeologists uncovering footing for a staircase, an early well, and the interior of the building during excavation after the removal of the floor boards. Constitution Hall was named a National Historical Landmark for its role in the 1857 Lecompton Constitution. The building is also listed in the National Register of Historic Places and as a National Historic Landmark. The hall was constructed in 1855 and functioned in a variety of different roles.
