It has been home to an array of intriguing characters. The distinctive architecture, storied history, and reputed hauntings make it a captivating subject of interest for historians, ghost hunters, and tourists alike.

Mazza Castle: Origins and Construction

Sam’s Castle was built of reinforced concrete in 1908 by Henry Harrison McCloskey, a prominent San Francisco lawyer. The castle was commissioned at the insistence of his wife in response to the 1906 San Francisco earthquake. The massive shaker left many residents seeking safer, more stable residences away from the city. McCloskey, inspired by the fortresses of Europe, chose a design that combined Gothic and Romanesque elements. Those choices resulted in the castle’s unique and imposing appearance.

Its hilltop location in Pacifica CA not only provided a strategic vantage point but also offers breathtaking views of the Pacific Ocean, adding to its allure.

Early Castle Residents and Uses

Initially, the castle served as a private residence for McCloskey and his family. After McCloskey’s death, the castle changed hands several times and was repurposed for various uses. However, its function evolved over time, reflecting the changing social and economic landscape of the region.

Pacifica: Bootleg Country

During Prohibition in the 1920s, Pacifica was home to several smuggling operations. McCloskey’s reportedly operated as a speakeasy, capitalizing on its secluded location. It was the host of clandestine parties and served illegal alcohol.

This period added an air of mystery and intrigue to the castle’s history, with rumors of hidden passages and secret rooms where illicit activities took place.

In the 1940s, the castle took on a new role as a brothel.  And less commonly known, an abortion clinic. This phase of its history is shrouded in secrecy and scandal, contributing further to its reputation as a site of dubious activities. The castle’s architecture, with its many nooks and crannies, provided an ideal setting for such operations, making it a well-known but covert destination.

During World War II, the Coast Guard took up residency at McCloskey’s using it as a barracks. Unfortunately, the site was significantly damaged by its human and K-9 in habitants. Sam Mazza had his work cut out for him at the time of his purchase in 1959.

Sam Mazza: A Colorful Owner

The castle’s most famous owner, and the one after whom it is now named, was Sam Mazza. Sam was born in 1915 in Chicago to Italian immigrant parents. His family later moved to San Francisco, where he developed an early interest in the arts. He transformed the castle into a hub of cultural and social activity.

Sam Mazza’s and Sons Construction

His professional career, initially, was grounded in the more practical field of carpentry and construction. Mazza founded his own company. That organization flourished under his leadership, allowing him to accumulate significant wealth. His success in the construction business enabled him to pursue his artistic interests.  He focused on the restoration of theaters which put his construction background and interest in art to good use.

Theater Restoration

Mazza was renowned for his efforts in refurbishing theaters back to their original glory. His construction company took on several restoration projects, revitalizing historic theaters that had fallen into disrepair. That work may have been the catalyst for his interest in purchasing and rehabbing the castle. Mazza’s commitment to preserving cultural heritage extended beyond his personal interests and had a lasting impact. His work ensured that these historic venues could once again serve as centers for the arts, contributing to the cultural vibrancy of the area.

Purchasing and Furnishing the Castle

Continuing his passion for intricate refinishing, Mazza saw the castle’s potential as a grand residence and a cultural venue. He bought the property and embarked on an extensive renovation project. His vision for the castle was not just as a home but as a space that celebrated art and culture.

Mazza’s eclectic taste is evident in the way he furnished the castle. He traveled extensively, collecting art, antiques, and curiosities from around the world. Each piece in his collection reflected his diverse interests and appreciation for different cultures. The castle’s interior became a showcase of these treasures. Rooms are filled with period furniture, ornate decorations, and unique artifacts. Some obtained through his theater connections.
