Downtown in St. Louis, Missouri — The American Midwest (Upper Plains)
Lynch's Slave Pen
In 1860 St. Louis's infamous slave trader Bernard M. Lynch opened his third and most notorious slave pen on this site. From 1849 to 1861 Lynch held enslaved people here in inhumane conditions, buying and selling them in St. Louis and other markets across the South. Lynch sent thousands of enslaved men, women, and children from Missouri and the Upper South down the Mississippi River to sell in Memphis, Natchez, and New Orleans. On September 1, 1861, the Union army seized his slave pen and transformed it into a Confederate prison.

2. Plaque will mark notorious St. Louis slave prison site near Busch Stadium (article). From NPR's St. Louis website, this talks about historians getting funds and help in getting the historical marker placed near Lynch's slave pen site. The idea was brought about in 2020 but it had been a five-year process getting donors. The St. Louis Cardinals baseball team were asked to contribute, and while supportive, they declined to be involved. (Submitted on February 2, 2026, by Jason Voigt of Glen Carbon, Illinois.)
