The War House is a former battery warehouse located at 624 27th Street South, on the corner of 7th Avenue South in Lakeview. It was owned by T. C. Cannon, who altered the original "warehouse" sign to give it its name.
Cannon, who formerly owned the TC bar across the street, periodically announced plans to open a new bar in the building. He primarily used it as a residence and also for storage and maintenance of his collection of Volkswagens and other vehicles. In 2001 he replaced the business's pole sign with a message reading "God Bless America. Support our Troops". During the 2016 presidential campaign he parked a scissor lift outside the building with signs supporting Donald Trump attached to its rails.
