Kind of tents, kind of geodesic, kind of awesome!

I have been reading a bit about Sarah Winchester and the house she built.
She designed and oversaw the construction of a massive house that was under constant construction for 38 years. It has 160 rooms but is thought to have had upwards of 500 rooms over the course of construction. After her infant child and husband died within a short time of each other she was haunted by all sorts of spirits. She built the house with a constant changing set of plans in an attempt to confuse the evil spirits and keep them from claiming her. Staircases lead no where, doors open onto solid walls and some rooms were sealed off.
I haven’t been to the house but I am putting it at the top of my list of unusual places to see. To read more about it go here or here
