My house was built in 1904 in St. Louis, USA. It has a brick exterior. Currently, one of the side walls has a narrow stack of bricks near the back of the house. The stack starts in the basement and goes through the second floor. It's about 9" x 20". I don't see any thing coming into or going out of it anywhere. It takes up precious space in our (too small) bathroom and (too small) kitchen.
Any ideas what it is, why its there and if it can be removed?
