Plattsmouth was founded prior to this around 1854 and the location of its East end at the Missouri river brought economic growth to the city with the possibilities for trade and travel. The downtown area grew with the construction of businesses and beautiful homes many of which are still occupied. Over 40 buildings in the Main Street Historic district are listed on the National Register of Historic places and representative of late 19th and early 20th century architecture.
