Est. 1891 · National Register of Historic Places (1975) · Designed by Thomas J. Welch · Main tower was highest point in Santa Cruz at completion · Site of 1907 murder-suicide: Frank McLaughlin killed stepdaughter Agnes, then himself
Major Frank W. McLaughlin built the Golden Gate Villa in 1891 as a summer residence on Beach Hill, high above the Santa Cruz coastline. Architect Thomas J. Welch designed the three-story Queen Anne structure — two full towers, one half-tower, and an elaborate eclectic Victorian facade — and the main tower briefly held the distinction of being the highest point in Santa Cruz.
McLaughlin had made his money as a mining engineer in the Sierra Nevada, working large-scale hydraulic gold operations. He hosted notable guests including Thomas Edison. But his most ambitious project — a massive hydraulic mining operation on the Feather River known as the 'Chinese Wall,' which promised enormous yields — collapsed in 1897 after yielding no gold despite years of investment. His wife Margaret died in November 1905 from chronic liver disease.
Two years later, on November 16, 1907, Agnes McLaughlin — Frank's adopted stepdaughter, then 33 years old — attended morning Mass at Holy Cross Church and returned to the villa to rest. McLaughlin entered her room while she slept and shot her in the head. He then wrote a note saying he had been planning the act every day for eight years, explaining his financial ruin, and including an unusual final request concerning his cat. He drank a cyanide cocktail.
The National Register of Historic Places listed the Golden Gate Villa in 1975, the same year Patricia Sambuck Wilder purchased it and converted the mansion to residential apartments. A stained glass window in the grand stairwell depicts Agnes McLaughlin; according to local historical accounts, strands of her hair were incorporated into the glass.

The Ghost of Agnes McLaughlin is the organizing legend of the Golden Gate Villa. Residents of the apartments that replaced the mansion's original layout have reported seeing the figure of a young girl in various parts of the building, identified by local lore with Agnes, who was 33 at the time of her death but sometimes described in the tradition as appearing younger.
The stained glass window in the grand stairwell gives the legend unusual physical grounding: a large jeweled-glass depiction of Agnes, reportedly incorporating strands of her actual hair, commissioned after her death. It remains in place in the converted building and is the most-cited feature in haunting accounts — multiple sources describe visitors pausing at the stairwell window before reporting a sense of presence.
The 1907 murder-suicide is well documented: the Santa Cruz Public Library local history archive holds photographs and period newspaper records of both deaths. The McLaughlin family's trajectory — fortune, financial collapse, the long premeditation McLaughlin described in his note — gives the villa's dark history a specificity that distinguishes it from vaguer haunting traditions. Local ghost tours include the villa as a stop, citing the stained glass and the documented history as the primary draws.

Watsonville, CA
Morris B. Tuttle, an orchardist who had relocated from Iowa, hired architect William Weeks to design this Victorian mansion in 1899. The property sat at the center of the Tuttle family's Pajaro Valley apple orchards and accumulated a series of violent deaths among family members over the following two decades.

Built 1881-1882 for Dominga de Goni Atherton after the death of her husband Faxon Atherton, the Queen Anne/Stick-Eastlake mansion stands at 1990 California Street and was San Francisco Landmark designation #70. Architect Charles J. Rousseau subdivided it into 13 apartments in 1923, and his widow Carrie Rousseau famously lived there with fifty cats until her death in 1974.
