Update: Armour, Hunter Meatpacking and the mule barns have been demolished as of July 2016. The status of the roundhouse is undetermined as of July 2016.
Here is a preview of much new material that I will be focusing on for the next couple of weeks. Above is the remnants of the Hunter Meatpacking Plant.
Above is an old B&O Railroad roundhouse buried in the underbrush along I-55.
Above are the spectacular ruins of the Armour Meatpacking Plant, inside the powerhouse.
And finally, the view of the city of St. Louis from the upper floor of the slaughterhouse.
