The Monroe City Mill was a grist mill located in Monroe City, Illinois, an unincorporated community in the historic Bluff Precinct of Monroe County, Illinois, United States. Monroe County was founded in 1816. Prior to that, the area was part of St. Clair County in the Illinois Territory. The Mill was built in 1800 and ceased operation in 1899. The stone foundation, including the water wheel arch, remain today on the original site. The Mill was located on the north bank of the Monroe City Creek, about one quarter mile below its source at a karst spring. The creek provided water to power the mill. The valley created by erosion from the creek is generally referred to as "the Monroe City Hollow." Over the years, the Mill has been referred to by a number of names, primarily reflecting ownership: Kinney's Mill from 1800 until about 1823; James' Mill from about 1823 until 1849; Garretson and Harlow's Mill from about 1850 to 1866; Ziebold's Mill from 1867 until about 1899. It was also generally known as the Monroe City Mill beginning in 1856 when the Town of Monroe City was platted. In 1798, Josiah Ryan built the original mill in the Monroe City Hollow about 2 miles west of the Monroe City Mill site, also on the banks of the Monroe City Creek.

Selma Hall also known as Selma Farm and Kennett Castle is a historic mansion and estate located in Jefferson County, Missouri along the Mississippi River. The mansion was designed in the style of Castello di Vezio by George I. Barnett and constructed in 1854 at a cost of $125,000 for Ferdinand Kennett. The mansion features a four-story tower constructed from locally quarried limestone by slave labor. Kennett and his brother Luther Kennett owned nearby lead mines, shot towers for the manufacture of bullets, steamboats, and slaves. The land was given to Ferdinand’s wife, Julia (née Deaderick), by her grandfather John Smith T, a wealthy lead miner and famous duelist. Ferdinand died in the mansion in 1861 before it was nearly destroyed during the Civil War by gun boats that fired upon the easy target from the Mississippi River below. The mansion was restored to its original appearance only to be destroyed again by fire in 1939, leading to a second restoration by then owner William O. Schock.Before the mansion was owned by Schock, it passed from Robert Brookings to W. K. Cavanaugh. The mansion and property was purchased by the Mississippi River Fuel Corporation in 1952 for $450,000 and it was used a conference center. The Mississippi River Fuel Corporation owned a controlling interest in the Missouri Pacific Railroad which was eventually purchased by the Union Pacific Railroad in 1982 who also used the mansion as a corporate retreat and conference center. In 2020, Union Pacific decided to cut costs and attempted to sell the property and adjacent 18-hole golf course for $25 million, the property sold for an undisclosed amount to an anonymous LLC in June 2021.
