Located in Cairo, Illinois, Magnolia Manor is a historic mansion dating back to the post Civil War period. It was built between 1869-1872 by mill merchant Charles A. Gallagher, who became very wealthy selling flour to the federal government during the war. He also sold his flour oversees including to Queen Victoria by way of her agent based in New York City. Gallagher also befriended Ulysses S. Grant, who was commander of 20,000 troops in Cairo between September 1861-February 1862. The house features many of its original furnishings. Another interesting fact about the house is that it has double walls with ten inches in between them to insulate the house and keep the dampness at bay. The mansion was listed on the National Register of Historic Places in 1969 and is now a museum operated by the Cairo Historical Association.
