In the 1800’s two neighbors in Alexandria Virginia fought tirelessly over an alley between their homes. As the story goes, when one neighbor went out-of-town, the other took that opportunity to build a house on the ally to stake his claim. In the end, the city decided neither neighbor owned that alley and the house belonged to them. Wikipedia’s version is slightly different and not half as fun (but probably closer to fact)! Built in 1830, today the Spite House in Alexandria Virginia, is privately owned. At 7 feet wide it is one of the narrowest homes in the world.
