Robert Frost once tried to convince people that “good fences make good neighbors.” It turns out it also works the other way around. Sometimes shitty neighbors make shitty fences — on purpose. There’s even a name for barriers created explicitly to piss off someone else: spite fences.
For instance, in 1876, railroad investor Charles Crocker built the mother of all spite fences to stick it to his less wealthy neighbor, an undertaker by the name of Nicholas Yung. Except for the lot owned by Yung, Crocker managed to buy up an entire city block, and all that was standing between him and his plans for total block domination was Yung, who refused to give up his sexy slice of real estate pie. In retribution, Crocker entombed the undertaker’s house in a concrete wall so high that it required support from buttresses.
