The Number 13
Which many believe was intended to ward off the Haunted Souls
Whether or not one believes in Mrs. Winchester’s superstitions about spirits, it’s harder to dismiss occurrences of the number 13 throughout the house. Many windows have 13 panes and there are 13 bathrooms, with 13 windows in the 13th Bathroom. There are also 13 wall panels in the room prior to the 13th Bathroom, and 13 steps leading to that bathroom. The Carriage Entrance Hall floor is divided into 13 cement sections. There are even 13 hooks in the Séance Room, which supposedly held the different colored robes Mrs. Winchester wore while communing with the spirits.

It’s interesting to note that Mrs. Winchester’s will had 13 parts and was signed by her 13 times!

Here are even more thirteens: 13 rails by the floor-level skylight in the South Conservatory, 13 steps on many of the stairways, 13 squares on each side of the Otis electric elevator, 13 glass cupolas on the Greenhouse, 13 holes in the sink drain covers, 13 ceiling panels in some of the rooms, and 13 gas jets on the Ballroom chandelier. (Mrs. Winchester had the thirteenth one added!)
