An odd structure purposefully commissioned to be so by the heir to the Winchester rifle fortune, the Winchester Mystery House is a ridiculous Victorian mansion with 160 rooms of various sizes and little utility, with dead-end hallways and a staircase that runs up to a ceiling all jammed together like a toddler playing architect. Apparently, Sarah Winchester spent 38 years constructing this mammoth white elephant because the spirits of the people killed by Winchester rifles told her to.
No expense was spared in the construction and the extreme results sprawl over 4 acres. Tours start every 30 minutes, and the standard hour-long guided mansion tour includes a self-guided romp through the gardens as well as entry to an exhibition of guns and rifles.
It’s west of central San Jose and just north of I-280, across the street from Santana Row.
