Tonight I read about Sarah Lockwood Pardee Winchester, an heir to the Winchester Repeating Arms fortune. She married into the family, had a daughter who died as a result of a childhood illness and lost her husband to tuberculosis. She inherited a substantial amount of money plus daily royalties and promptly went crazy. The real crazy part is that she believed there to be a curse and a medium told her the only way to fight the curse was to build a house and continually add onto it. The result turned into a 160 room mansion with staircases going to nowhere, fireplaces with no chimneys, lots of incorporations of the number 13, and other such oddities. You can read a lot of details here or take a virtual tour of the house here.
