You’d never guess that this luxurious, adobe-style hotel situated on six lush acres in the heart of Santa Fe’s Historic District has a sinister past. Long before it was a dog-friendly, AAA Four Diamond award-winning resort, La Posada de Santa Fe was the home of Julia Staab. After the miscarriage of her seventh son and several previously unsuccessful pregnancies, Julia fell into a deep depression and hid away in her room until her death in 1896. According to reports from employees and guests, Julia’s spirit never left. She haunts the mansion, now home to the hotel’s dining options aptly named Staab House and Julia - A Spirited Restaurant and Bar. In these establishments, witnesses have seen glasses flying off shelves and waiters’ trays being pushed out of their hands.
