Which California historical landmark in San Jose had 160 rooms when its original owner died in 1922?

The Winchester Mystery House is a mansion in San Jose, California, that was once the personal residence of Sarah Winchester, the widow of firearms magnate William Wirt Winchester. The Victorian and Gothic-style mansion is renowned for its size and its architectural curiosities.

It is sometimes claimed to be one of the "most haunted places in the world", but there is no evidence to support this belief. Much of the lore regarding the Winchester House and its owner is fanciful, unverified, and often provably false.

Its construction took place between 1884 and 1906, mostly led by Sarah Winchester.

When Winchester died in 1922 the house had 160 rooms, 2,000 doors, 10,000 windows, 47 stairways, 47 fireplaces, 13 bathrooms, and 6 kitchens.

Several renovations have taken place since. The house became a tourist attraction nine months after Winchester's death in 1922.
