 The current courthouse, which sits on the same site as the 1850 building, was erected in 1905.The DeKalb County Circuit Court came into existence in June 1839 when the first session of court met in Sycamore's first courthouse building, though the building was somewhat incomplete.At first, it seemed, that Sycamore might not be the location of the DeKalb County Courthouse; other towns were vying for the county seat title.
